GATE 2020: Analog Circuits Rapid Quiz - 2 (App update required to attempt this test)

For the given circuit the transfer characteristics are  

For the given circuit the op-amp has CMRR=60dB. Determine the magnitude of the output voltage (in mV)

A transistor with npn configuration has a capacitance of 0.4 pF. The cut off frequency when the gain is unity is 800 MHz. The collector current used as biasing is 2 mA. The value of C_π (in pF) at room temperature is______.

An IC-555 is connected by an exterior resistance and capacitors as shown in figure below. It is built to provide an output pulse with duration of 0.825 ms, when a negative trigger pulse is applied at the second pin (2) of the 555-IC. If the value of R = 7.5 kΩ, then the value of the capacitor (C), connected between pin number 6 and ground, is ….. (in μF)

Find the value of V_{0…………….} (in V) if the op-amp is ideal.
