====== Multistage amplifier compensation ====== {{highgainamp1.png?300}} Determine the gain of the amplifier in (a) when the transconductance of the inverter tends to infinity. Build the amplifier in (a) with an ideal gain of 2 and R1 in 5kΩ to 10kΩ range. Use a 6V supply for this experiment. Measure the gain error. **Connect inputs of unused inverters to ground** {{highgainamp3a.png?400}} The gain error can be reduced by increasing the loop gain. Use another inverter in cascade (and a unity gain inverter for negative feedback) as shown above and measure the circuit. Does it result in a better amplifier? {{highgainamp3b.png?400}} Compensate the amplifier by connecting a capacitor C1 to ground as shown above. Adjust its value for 10% overshoot. Use a 100mVpp square wave input for this measurement. {{highgainamp3c.png?400}} Compensate the amplifier by connecting a capacitor C2 across the second stage as shown above. Adjust its value for 10% overshoot. Comment on the compensation capacitor values C1 and C2 in the two cases.
