1. The drain of an n-channel MOSFET is shorted to the gate so that VGS = VDS. The threshold voltage (VT) of MOSFET is 1 V. If the drain current (ID) is 1 mA for VGS = 2V, then for VGS = 3V, ID is

A. 2 mA
B. 3 mA
C. 9 mA
D. 4 mA

I think D is ans 

2. A 1 kHz sinusoidal signal is ideally sampled at 1500 samples/sec and the sampled signal is passed through an, ideal low-pass filter with cut-off frequency 800 Hz.The output signal has the frequency

A. zero Hz
B. 0.75 kHz
C. 0.5 kHz
D. 0.25 kHz
I think c is ans 

3. Let A = 1111 1010, B = 0000 1010 be two 8-bit 2’s complement numbers. Their product in 2’s complement is:

A. 1100 0100
B. 1001 1100
C. 1010 0101
D. 1101 0101
I think A is ans
