Abstract
A high-speed, fully-floating, current source/sink utilized a current mode operational amplifier to drive a power MOSFET without ringing or instability. The output of the current mode op amp is directly connected to the MOSFET gate. The current source relies on an optical link to enable an analog switch to generate carefully controlled pulse width characteristics at the positive input of the op amp.
