Function Generator Amplifier

Oftentimes, you need the ability to beef up the output of your function generator. Maybe, you need to drive a transformer winding or something with relatively low impedance. The source resistance of a typtical signal generator is way too high for such things. This amplifier will increase the output current and output voltage of the

Comparators

A comparator is a device that compares two voltages and determines which one is higher. This can be used for indicating if a varying voltage exceeds a certain level with respect to a fixed reference voltage. Comparators are mostly but not always comprised of op-amps. The reason is the very high open loop gain (gain
