Abstract
A remote differential voltage sensing circuit having a voltage input (Vin) and a voltage output (Vout), comprises a dual differential input stage including a common-source or common-collector differential input stage in parallel with a common-gate or common-base differential input stage. The common-source or collector differential input stage has differential inputs, one coupled to the voltage input (Vin) and the other coupled to the voltage output (Vout). The common-gate or common-base differential input stage has differential inputs, one coupled to a local ground (Agnd) and the other coupled to a remote ground (Rgnd). An output stage is driven by an output of the dual differential input stage and produces an output voltage at the voltage output (Vout). A compensation network is coupled between the voltage output (Vout) and the output of the dual differential input stage.
