Abstract
A current sensing circuit includes: a first controlled device; a first controlled device; a first current mirror configured to cause a first mirror current to flow through a first load device based on a first control signal received by the first controlled device; a second controlled device; a second current mirror configured to cause a second mirror current to flow through a second load device based on a second control signal received by the second controlled device; and an amplifier configured to output a voltage signal based on the first mirror current flowing through the first load device and the second mirror current flowing through the second load device. The first control signal is substantially proportional to a first drive signal applied to a first controlled remote device, and the second control signal is substantially proportional to a second drive signal applied to of a second controlled remote device.
