Abstract
An ultrasound transmitter including intrinsic output zeroing is disclosed herein. A transmitter for generating ultrasound signals includes a first transmitter output driver and a first transmitter input driver. The first transmitter output driver includes an N-type device serially coupled to a P-type device. The first transmitter input driver includes an N-type device serially coupled to a P-type device. An output of the first transmitter input driver is coupled to an input of the first transmitter output driver. The first transmitter output driver drives an output of the transmitter to a first voltage and the first transmitter input driver drives the output of the transmitter to a second voltage while the first transmitter output driver is disabled.
