The circuit shown in Figure is a simplified model of a "dual-mode" oscillator [28]. The voltage-dependent current source models a transistor. The circuit oscillates if Z_in goes to infinity for s = j_ω.

(a) Determine the input impedance Z_in.

(b) Set the denominator of Z_in to zero for s = j_ω and obtain the startup condition and the two oscillation frequencies.
