The section contains analog circuits questions and answers on Resistor networks, transistor MOSFET, current mirror, Opamp, and RC circuits (transient analysis). Answer 1. Answer 2. If RC >> T, then the circuit acts as an integrator. If RC << T, Here the time constant is very small, so the capacitor will be charged very fast and the output voltage almost follows the input voltage. Answer 3. Given a DAC circuit so the value 1010 corresponds to the 10 in decimal and it is 4-bit. Therefore the least significant bit will be equaled to Vred/16 = 8/16 = 0.5V. Hence the value 1010 is 0.5*10 = 5V. One more method by using a superposition theorem also it can be solved. Answer 4. Vthe = 400mV. The
