Frequency Response Of BJT Amplifiers
The voltage gain of an amplifier varies with signal frequency due to the effect of variations in circuit capacitive reactance with signal frequency in the output. The curve drawn …
Class B Power Amplifier
Class B amplifier is a type of power amplifier where the active device (transistor) conducts only for half cycle obey input signal. That means the conduction angle is 180 …
Frequency response of OP-AMP
OP-AMP Bandwidth, frequency response & gain bandwidth product are key parameters for any circuit. Typically, OP-AMPs are used for comparatively low frequency circuit but with the performance of these …
JFET as an amplifier
JFET as an amplifier- The weak signal is applied between gate and source, and amplified output is obtained across drain and source terminal. For proper operation of JFET gate …
Construction of depletion type MOSFET
Depletion type MOSFET- A slab of P type materials formed from a silicon base and refer towards substrates. It is the foundation on which device is constructed. In some …
Working of JFET
Working of JFET- The two P-N junctions at the sides form two depletion layers. The current conduction by charge carrier i.e. electrons in case of N-channel JFET is thought …
Difference between BJT and FET
BJT- Bipolar transistor Current conduction takes place due to both electrons and holes BJT has negative temperature coefficient BJT has high volt gain BJT has no current gain Low …
