Choose the right statement: a) An ideal OPAMP has an zero input impedance, zero output impedance and an infinite open loop gain. b) An ideal OPAMP has an infinite input impedance, zero output impedance and an infinite open loop gain. c) An ideal OPAMP has an infinite input impedance, infinite output impedance and an zero open loop gain. d) An ideal OPAMP has an zero input impedance, zero output impedance and an infinite open loop gain.

You input a short 3V voltage pulse into a peak-hold circuit at t=0 and measure the output. What is the output amplitude at t=RC? (Give your answer in Volts with two significant figures.)

The following circuit is a passive peak hold circuit:      True/False: The  performance of the passive peak hold circuit changes negligibly as it interacts with other components (i.e. loading effects).

 Calculate Vout if the JFET Vc = -7 V, Vin = 10 V. The Vth for the JFET is -5V. Enter your answer in volts to the nearest 0.1 V.

A JFET is connected to an op-amp circuit as shown. The JFET’s resistance for different gate voltages is shown in the table. If a 2 VPP sine wave with a -1 V DC offset is given as input to the op-amp, what is the MINIMUM VALUE of the output voltage when VGS is set to -200 mV? VGS RJFET 0 200

You are viewing a 1kHz sine wave on an oscilloscope. What should be the time/division (in milliseconds/division) to view 2 full cycles in 4 horizontal divisions?

What would be the value of Vout if Vin is a DC voltage as shown? Express your answer in volts to the nearest 0.1 V.   

Find the equivalent resistance of the network shown below. Express your answer in Ohms, rounded to the nearest Ohm.   

Why would you expect frog populations to be able to grow quickly? Would you describe mice as r-selected or K-selected and why? 4pt

The magnitude of an op-amp’s output can exceed the supply voltages.
