What is peaking circuit?
[′pēk·iŋ ‚sər·kət] (electronics) A circuit used to improve the high-frequency response of a broad-band amplifier; in shunt peaking, a small coil is placed in series with the anode load; in series peaking, the coil is placed in series with the grid of the following stage.
What is meant by shunt peaking?
Definition of Shunt Peaking -> A technique used to improve high-frequency response in which a peaking coil is placed in parallel (shunt) with the output signal path.
How does inductor help in improving bandwidth?
The inductor introduces a zero in that increases the impedance with frequency, compensates the decreasing impedance of , and thus extends the 3 dB bandwidth. An equivalent explanation for increased bandwidth is reduced rise- time.
What do you mean by precision rectifier?
From Wikipedia, the free encyclopedia. The precision rectifier is a configuration obtained with an operational amplifier in order to have a circuit behave like an ideal diode and rectifier. It is very useful for high-precision signal processing.
What is a peak rectifier?
Definition: Peak detector circuits are used to determine the peak (maximum) value of an input signal. It stores the peak value of input voltages for infinite time duration until it comes to reset condition. Rectifier circuits usually provide an output in proportion to the average value of the input. …
What is inductive peaking?
A novel negative current feedback mechanism is used to reduce the value of the series-peaking inductance at the cost of current gain. The proposed techniques do not affect the supply voltage and the DC biasing conditions.
Why it is called precision rectifier?
The precision rectifier will make it possible to rectify input voltage of a very small magnitude even less than forward voltage drop of diode. Rectifier circuits used for circuit detection with op-amps are called precision rectifiers.

What is full wave rectifier?
A full wave rectifier is defined as a type of rectifier that converts both halves of each cycle of an alternating wave (AC signal) into a pulsating DC signal. Full-wave rectifiers are used to convert AC voltage to DC voltage, requiring multiple diodes to construct.
What is called precision rectifier?
The precision rectifier is a configuration obtained with an operational amplifier in order to have a circuit behave like an ideal diode and rectifier. It is very useful for high-precision signal processing.
What is the purpose of a cooling coil?
A cooling coil is a device intended to allow the contents of the coil to cool as they move through it. Cooling coils can be used in materials processing to control the temperatures of various components, and they are also employed in heating and cooling systems where space is at a premium and other cooling arrangements are not feasible.
Which is the correct definition of rated coil voltage?
(Rated Coil Voltage) A single value (or narrow range) of source voltage intended by design to be applied to the coil or input. (Pull-In Voltage or Must Operate Voltage) As the voltage on an unoperated relay is increased, the value at or below which all contacts must function (transfer).
What is the kids definition of a coil?
coiled; coiling. Kids Definition of coil (Entry 2 of 2) 1 : to wind into rings or a spiral coil a rope. 2 : to form or lie in a coil The cat coiled up before the fireplace.
How are the contacts on an ignition coil driven?
The contacts are driven off a shaft that is driven by the engine camshaft, or, if electronic ignition is used, a sensor on the engine shaft controls the timing of the pulses. The amount of energy in the spark required to ignite the air-fuel mixture varies depending on the pressure and composition of the mixture, and on the speed of the engine.
