Wire Wound Resistors
Many precision resistors utilize a wire-wound construction, where the
resistance is determined by the type and length of wire wrapped around a
spool. This form of construction allows for high precision of resistance,
with low temperature sensitivity if certain metal alloys are used for the
wire.
Unfortunately, though, wrapping wire around a spool forms a coil, which will
naturally possess a significant amount of inductance. This is generally
undesirable, as we would like to have resistors possessing only resistance,
with no "parasitic" properties.
There is, however, a special way in which a wire coil may be wound so as to
have almost no inductance. This method is called bifilar winding, and it is
common in wire-wound resistor construction.

Circuit Components
Stray Capacitance
All inductors contain a certain amount of stray capacitance due to turn-to-turn and
turn-to-core insulation gaps. Also, the placement of circuit conductors may create
stray capacitance. While clean circuit layout is important in eliminating much of this
stray capacitance, there will always be some that you cannot eliminate.
If this causes resonant problems (unwanted AC oscillations), added resistance may be
a way to combat it. If resistor R is large enough, it will cause a condition of antiresonance, dissipating enough energy to prohibit the inductance and stray
capacitance from sustaining oscillations for very long.

Schottky diodes are constructed of a metal-to-N junction rather than a P-N
semiconductor junction. Also known as hot-carrier diodes, Schottky diodes
are characterized by fast switching times (low reverse-recovery time), low

and low junction capacitance.
The schematic symbol for a Schottky diode is shown in Figure below.

Transistor Cases and Insulation
Since the TO-220 and TO-247 slugs, and the TO-3 case are connected to
the collector, it is sometimes necessary to electrically isolate the
these from a grounded heatsink by an interposed mica or polymer
washer. The datasheet ratings for the power packages are only valid
when mounted to a heatsink. Without a heatsink, a TO-220 dissipates
approximately 1 watt safely in free air.

Triode – Three Elements
De Forest's Audion tube came to be known as the triode tube, because it
had three elements: filament, grid, and plate. The low-voltage AC
signal connected between the grid and cathode alternately
suppresses, then enhances the electron flow between cathode and
plate. This causes a change in voltage on the output of the circuit
(between plate and cathode). The AC voltage and current magnitudes
on the tube's grid are generally quite small compared with the
variation of voltage and current in the plate circuit. Thus, the triode
functions as an amplifier of the incoming AC signal (taking highvoltage, high-current DC power supplied from the large DC source on
the right and "throttling" it by means of the tube's controlled
conductivity).
Tetrode – Four Elements
When connected to ground through an external capacitor, the screen
had the effect of electro-statically shielding the grid from the plate.
Without the screen, the capacitive linking between the plate and the
grid could cause significant signal feedback at high frequencies,
resulting in unwanted oscillations. The screen, being of less surface
area and lower positive potential than the plate, didn't attract many
of the electrons passing through the grid from the cathode, so the
vast majority of electrons in the tube still flew by the screen to be
collected by the plate:
Pentode – Five Elements
The suppressor's job was to repel any secondarily emitted
electrons back to the plate: a structural equivalent of
the beam power tube's space charge. This, of course,
increased plate current and decreased screen current,
resulting in better gain and overall performance. In
some instances it allowed for greater operating plate
voltage as well

FET – Field Effect Transistor
Uni Junction Transistor
All FETs have a gate, drain, and source terminal that correspond roughly to the
base, collector, and emitter of BJTs. Aside from the JFET, all FETs also have
a fourth terminal called the body, base, bulk, or substrate. This fourth
terminal serves to bias the transistor into operation; it is rare to make nontrivial use of the body terminal in circuit designs, but its presence is
important when setting up the physical layout of an integrated circuit. The
names of the terminals refer to their functions. The gate terminal may be
thought of as controlling the opening and closing of a physical gate. This
gate permits electrons to flow through or blocks their passage by creating or
eliminating a channel between the source and drain. Electrons flow from the
source terminal towards the drain terminal if influenced by an applied
voltage.

RTL IC Logic
RTL – Resistor Transistor Logic – The Earliest integrated circuit logic.
The obvious disadvantage of RTL is its high current dissipation when
the transistor conducts to overdrive the output biasing resistor. This
requires that more current be supplied to and heat be removed from
RTL circuits. In contrast, TTL circuits minimize both of these
requirements.
TTL IC Logic
TTL– Transistor – transistor logic contrasts with the preceding resistor–
transistor logic (RTL) and diode–transistor logic (DTL) generations by
using transistors not only to amplify the output but also to isolate the
inputs. TTL devices consume substantially more power than
equivalent CMOS devices at rest, but power consumption does not
increase with clock speed as rapidly as for CMOS devices.
CMOS IC Logic
Two important characteristics of CMOS devices are high noise immunity
and low static power consumption. Significant power is only drawn
when the transistors in the CMOS device are switching between on
and off states. Consequently, CMOS devices do not produce as much
waste heat as other forms of logic, for example transistor-transistor
logic (TTL) or NMOS logic, which uses all n-channel devices without
p-channel devices. CMOS also allows a high density of logic functions
on a chip. It was primarily this reason why CMOS won the race in
eighties and become the most used technology to be implemented in
VLSI chips.
