Question 5

In the circuit shown below, N is a two-port network. If I = 1 A, then the values of V₁ and V₂ will be

Take the Y-parameter of two port network N, as

Question 6

Consider a silicon PN junction at T = 300 k with acceptor concentration of N_a = 10¹⁸ cm^–3 and donor concentration of N_d = 10¹⁵ cm^–3. If we change the acceptor doping concentration to N_a = 10¹⁶ cm^–3 by keeping all other parameters constant, then the percentage decrease in built – in potential of the junction will be equal to ________ %.

₍Assume n_i = 1.5 × 10¹⁰ cm^–3, kT = 0.026 eV)

Question 7

The amplifier circuit shown in the figure is implemented using a compensated operational amplifier (op-amp), and has an open-loop voltage gain, and an open-loop cut-off frequency, f_c= 8 Hz. The voltage gain of the amplifier at 15kHz, in V/V, is ______.

Question 8

Five telemetry signals, each of bandwidth 240 Hz are to the transmitted simultaneously by binary 8 bit PCM. The signals must be sample at least 20% above the Nyquist rate. Framing and synchronization requires an additional 0.5% of extra bits. The bit rate (in kbps) of the multiplexed signal is…………..
