Abstract:SummaryIn this article, a compact integrated high‐voltage (HV) pulser is presented, which can serve as an actuator in area‐limited medical ultrasound imaging applications. The proposed HV pulser is capable of producing bipolar return‐to‐zero (RTZ) HV pulses with a maximum peak‐to‐peak amplitude of 60 V. A novel RTZ stage including a new transistor gate–source protection scheme is used in this work, resulting in a reduced die area by enabling the use of an embedded transmit/receive (T/R) switch and obviating th… Show more
