A capacitor is placed in parallel with \(R_{L}\) in the circuit in Figure P7.24. The capacitance is \(C_{L}=10 \mathrm{pF}\). The transistor parameters are the same as given in Problem 7.24.

(a) Determine the upper \(-3 \mathrm{~dB}\) frequency.

(b) Find the high frequency value at which the small-signal voltage gain magnitude is one-tenth the midband value.

Data From Problem 7.24:-

The parameters of the transistor in the circuit in Figure P7.24 are \(V_{B E}(\) on \()=0.7 \mathrm{~V}, \beta=100\), and \(V_{A}=\infty\).

(a) Determine the quiescent and small-signal parameters of the transistor.

(b) Find the time constants associated with \(C_{C 1}\) and \(C_{C 2}\).

(c) Is there a dominant \(-3 \mathrm{~dB}\) frequency? Estimate the \(-3 \mathrm{~dB}\) frequency.
