Abstract: Methods and apparatus for reducing a transient glitch in ultrasound applications are disclosed. An example apparatus includes a transducer to (A) output a signal during a transmit phase and (B) receive a reflected signal corresponding to the signal during a receive phase; a receiver switch coupled to the transducer at a first node, the receiver switch to (A) open during the transmit phase and (B) close during the receive phase; and a clamp coupled to the transducer at the first node, the clamp to provide a high impedance during the transmit phase and the receive phase and provide a low impedance during a transient phase.
