In the circuit shown in Fig. is a finite gain amplifier with a gain of K, a very large input impedance, and a very low output impedance. The input impedance of the feedback amplifier with the feedback impedance Z conducted as shown will be

A common-emitter amplifier with an external capacitor C_C connected across the base and the collector of the transistor is shown in Fig.

Transistor data g_m = 5mA/V, $${r_\pi }\, = \,200K\Omega, $$ $${C_\pi }\, = \,1.5$$ pF and $$C\mu \, = \,0.5$$ pF determine the upper cutoff frequency f_H of the amplifier

A JEFT with V_P = -4V and I_Dss = 12mA is used in the circuit shown in Fig. Assuming the device to be operating in saturation, determine I_D, V_DS and V_GS

Value of R in the oscillator shown in the given figure. So chosen that it just oscillates at an angular frequencies of' "$$\omega $$". The value of "$$\omega $$" and the required value of R will respectively be
