The ac schematic of an NMOS common-source stage is shown in the figure below, where part of the biasing circuits has been omitted for simplicity. For the n -channel MOSFET M, the transconductance g_m = 1 mA/V, and body effect and channel length modulation effect are to be neglected. The lower cutoff frequency in Hz of the circuit is approximately at

In a voltage-voltage feedback as shown below, which one of the following statements is TRUE, if the gain k is increased?

In the circuit shown below, what is the output voltage (v_out ) if a silicon transistor Q and an ideal op-amp are used?

In the circuit shown below the op-amps are ideal. Then V_out in Volts is
