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 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
3. Let A = 1111 1010, B = 0000 1010 be two 8-bit 2’s complement numbers. Their product in 2’s complement is:
I think A is ans
A. 1100 0100 B. 1001 1100 C. 1010 0101 D. 1101 0101 |
