2. A single transistor amplifier is shown in the circuit to the right. The input is a 100 kHz sine wave from a very low impedance source, with a 1 mV peak-to-peak amplitude. hfe, the forward current gain of the transistor, is 300. The base reverse leakage current is 1 nA. The ideality factor for the base-emitter diode is 2, so nkT= 50 mV. a. What are the voltages relative to ground and the currents flowing into, into, and out from the collector, the base, and the emitter, respectively? b. What is the impedance of the 1 µF capacitors at 100 kHz and what effect will this have on the gain of the amplifier? c. What is the gain of the amplifier and how does it depend on the hfe of the transistor? Luff Vin maits Ik { +V₁ = +15V املا Vo Sik Y 1 Fb V₂ I m Vout MF 2K = 250 hfő - -15V --Y₂
