Voltage Divider Impedance Matching

01:02:32

> This circuit demonstrates how to match a high source impedance to a low load impedance without using a transformer. A voltage divider simulates a weak, high-impedance source. An op-amp configured as a voltage follower buffers the signal, presenting high input impedance to the source and low output impedance to the load. This allows the low-impedance load to receive the signal cleanly without draining or distorting the source.

Why not just have feedback instead of using a comparator powered from 2V?

Also what does that 1K resistor do at the inverting input in this case? I’ve heard it is sometimes used as a form of impedance matching.

The 1K resistor at the inverter is to prevent overheating of the OP Amp, otherwise you could just use any given voltage divider and match impedance with resistance.
