2 EE 311 Multistage Amplifier Design Specifications Voltage Gain A V > 300 @ 1 kHz Output Voltage V out peak-to-peak > V CC / 3 for a single power supply design V CC / 2 for a dual power supply design with V CC EE Where V EE = -V CC Lower half-power frequency f L < 50 Hz Upper half-power frequency f H > 100 kHz Input Resistance R i > 200 k @ 1 kHz Output Resistance R o < 100 @ 1 kHz. Note change from EE 353 Spec. Load Resistor R L = 100. Note change from EE 353 Spec. Total Power Supply Current < 250 mA. Note change from EE 353 Spec. No coupling capacitors except to signal source and 100 Ω load.

Unformatted text preview: One bypass capacitor allowed. Use actual transistor models such those for Q2N3904, Q2N3906, J2N3819, etc. Lab 6 in EE 311 During Next Week. 3 Summary 4 EE 311 Multistage Amplifier Scorecard R b = Thevenin Equivalent Resistance seen looking out from base to ground. R c = Thevenin Equivalent Resistance seen looking out from collector to ground. R e = Thevenin Equivalent Resistance seen looking out from emitter to ground.
