Abstract
A power harvesting circuit for use in an open drain transmitter circuit is configured to generate two distinct harvested supply voltages at different voltage levels along with two distinct cascode voltages at different voltage levels. The harvested supply voltages are used to power circuitry in the transmitter circuit. The cascode voltages are used to bias cascode transistors in the open drain circuitry for different channels.
