You are given the circuit configuration, and the types of transistors to use, but not the resistor values. The circuit is below:
In order for the amplifier to work properly and with good power consumption, you need to design the resistors so that the circuit meets the following specifications:
• The current through Q1 should be close to 0.5 mA.
• The current through Q2 should be close to 0.5 mA.
• The current through Q3 should be close to 1.0 mA.
• The voltage at V3 should be close to 0.0V.
• The voltage at V5 should be close to -2.0V.
• The voltage at V7 should be close to 1.0V.
First, start by doing a hand analysis of the circuit, assuming that β=∞ (no base current) and using the standard assumption that the base-emitter junction is at 0.7V when not in cutoff. Use this to get a rough value for the resistors.
