Using the components listed below, design an amplifier having a voltage gain of −10 ± 20 percent. The input impedance is required to be as large as possible (ideally, an open circuit). Remember to use practical resistance values. Cascade a non-inverting stage with an inverting stage. 1) Standard 5%-tolerance resistors. 2) Standard 1%-tolerance resistors. (Don’t use these if a 5%-tolerance resistor will do, because 1%-tolerance resistors are more expensive.) 3) Ideal op-amps. 4) Adjustable resistors (trimmers) having maximum values ranging from 100 Ω to 1 MΩ in a 1–2–5 sequence (i.e., 100Ω, 200Ω, 500Ω, 1 kΩ, etc.). Don’t use trimmers if fixed resistors will suffice.
