Trade-offs Between CMOS, JFET, and Bipolar Input Stage …

WebMOSFETs are used in the design of the chopper circuit. Advantages of MOSFET. MOSFETs operate at greater efficiency at lower voltages. Absence of gate current … WebHigh impedance inputs are inputs that, as much as possible, don't take power from the source of the signal, by not allowing much current to flow. Generally, when you do need a significant amount of power, it is taken not from the controlling input signal, but from the power supply, separately connected.
