Abstract
An ultrasound front end circuit (2000) which includes a multiple winding transformers (N1, N2, N3, N4) to accomplish both transmit pulse generation and transmit/receive switching. An additional set of transformer windings and switching transistors (1103) allows logical selection between one of two transmit levels.
