Addition of pentavalent impurities to a semiconductor creates many

For an ideal op-amp, the slew rate is _____ V/s

The most commonly used motors in power electronics systems are:

Consider a silicon diode with n=1. The current changes from 0.1 mA to 10 mA. Find the approximate change in the voltage.

Determine the value of the diode small-signal resistance rd at bias current equal to 2mA.

(Assume n = 1 and the answer should be in ohms)

What type of feedback is employed in an oscillator?

In a double side-band (DSB) full carrier AM transmission system, if the modulation index is doubled, then the ratio of total sideband power to the carrier power increases by a factor of 

In a BJT based current mirror circuit, calculate the output current I0(in mA, rounded off to 2 decimal places) if the input reference current(Iref) is 5mA.

(given: beta = 99 (current gain of the transistor))

The threshold voltage of an n-channel MOSFET can be increased by

 A BJT in a common-base configuration is used to amplify a signal received by a 50Ω antenna. Assume kT/q = 25 mV. The value of the collector bias current (in mA) required to match the input impedance of the amplifier to the impedance of the antenna is
