摘要:
An ultrasonic transceiver system including a transducer, a receiver coupled to the transducer, a transmitter having an output terminal coupled to the transducer, and a transmit/receive switch configured to isolate the receiver from the transmitter during transmission. The transmitter includes an amplifier and an output stage. The output stage includes a source follower transistor having a drain coupled to a supply terminal, a gate coupled to an output of the amplifier, and a source coupled to an output terminal, along with a power stage transistor having a source coupled to the supply terminal, a gate coupled to the drain of the source follower transistor, and a drain coupled to the output terminal. The output stage further includes a parallel source follower transistor having a drain coupled to the supply terminal, a gate coupled to the input terminal, and a source coupled to the output terminal.
