Abstract
Encoding of a dual mode digital signal for transfer using a dual mode super source follower circuit to drive the signal across a pulse transformer is presented. The dual mode signal includes data in one mode and power/control in the other mode. In the power/control mode the magnitude of the signal pulses are greater than the magnitude of the data pulses. Thus, the current sinking deficiencies of the super source follower may introduce waveform irregularities when transitioning from the high of the power pulse to the high of the data pulse. An encoding method described herein uses a return to zero scheme to avoid such waveform irregularities during power to data transitions.
