... summing their currents. The common collector is held at 3.0VDC by 4/4 of U3. The current is sensed by R15, so that the output of 4/4 U3 will swing by 1 volt/mA of collector current. Radiated noise at the chop frequency is greatly reduced, as all lines going to the chopper head are held at constant v ...
