Of course, this gate voltage is not sufficient for a good switch-on operation. In order to achieve a low switch-on resistance (Drain Source ON resistance, R DSon), a considerably higher gate voltage must be applied, e.g. 10 V.In order to control the MOSFET with high impedance, i.e. to switch it off, the gate voltage must be permanently and significantly below the threshold voltage. Intoduction. An operational amplifier, or op-amp for short is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.In this configuration, an op-amp produces an output potential that is typically hundreds of thousands of times larger than the potential difference between its input terminals, and is a voltage amplifying device.
