For the circuit shown in the figure below, assume that D₁, D₂ and D₃ are ideal. v(t) = π sin (100πt) V



The DC components of voltages v₁ and v₂, respectively are

A current controlled current source (CCCS) has an input impedance of 10 Ω and output impedance of 100 kΩ. When this CCCS is used in a negative feedback closed loop with a loop gain of 9, the closed loop output impedance is

Given, V${}_{gs}$ is the gate-source voltage, V${}_{ds}$ is the drain source voltage, and Vₜₕ is the threshold voltage of an enhancement type NMOS transistor, the conditions for transistor to be biased in saturation are

A common-source amplifier with a drain resistance, R${}_D$ = 4.7 kΩ is powered using a 10 V power supply. Assuming that the transconductance, g${}_m$, is 520 μA/V, the voltage gain of the amplifier is closest to:

In the circuit shown, the diodes are ideal, the inductance is small and I₀ ≠ 0 . Which one of the following statements is true?
