Synchronous system to measure microOhm

Synchronous system to measure microOhm
The circuit in the diagram uses a synchronous-detection scheme to measure low-level resistances. Other low-resistance-measuring circuits sometimes inject unacceptably large currents into the system on test. The present circuit synchronously demodulates the voltage drop across the system on test and can therefore use very low currents while measuring the resistance.
