Abstract
A digital switched current source is coupled to a programmable current source-driver and controlled by waveforms stored in the programmable and floating complementary sourcing and sinking current source-driver. A plurality of complementary P- and N-MOSFET is coupled to the programmable floating current source driver. The transformer-less programmable ultrasound transmit beamformer integrated circuit is provided and directly coupled to the plurality of transducers.
