Draw the circuit of a common source amplifier, which is biased by a MOSFET current mirror, and which uses only one capacitor and two resistors (including the RREF of the current mirror). Assume that the input to the amplifier is a zero-DC signal. Then, design the amplifier to achieve a gain Avo--gRo =-4V/V, and an output resistance Ro-Ro-1K. Ignore channel modulation. Assume that all MOSFETS are identical with VIN-1V, and Kn = 2mA/V. Use Vo = 5V and Vs =-5V....

1. Draw the schematics of forward-biased and negative-biased diodes. Show the polarity of voltage source (positive and negative terminal of the source), the position of Fermi levels and the current direction. Explain why there is a small current flow when a p-n junction is under reverse bias. 2. A p-n junction can be made by diffusing acceptor atoms into an n-type semiconductor. Suppose that boron is diffused into a silicon wafer doped with arsenic at 1015 cm-3 such that the...

Q1 Which of the following is true for a MOS capacitor with a P-type body? Select one: a. The charge in the inversion layer stays approximately constant as the gate voltage is increased above the threshold voltage b. The charge in the depletion region is proportional to the square root of the depletion region width, assuming that the body is uniformly doped c. In inversion, the total charge is equal to the sum of the charge in the depletion region...

4. A p-type semiconductor has positive charge carriers but is electrically neutral. Similarly an n-type semiconductor has negative charge carriers but is electrically neutral. When they are put in contact (making a diode), statistical forces cause some of the charge carriers to migrate to the opposite semiconductor. The charge carriers move until an E-field is created to stop the migration. This E-field creates a depletion region near the junction where there are no charge carriers. If a forward voltage is...
