Abstract: An ultrasonic sensing circuitry is disclosed which includes an ultrasonic sensor circuit, an input circuit, a reset circuit, a storage circuit, a selection circuit, a source follower, and a compensation circuit. The ultrasonic sensor circuit generates a sensing voltage corresponding to a received ultrasonic signal to provide the sensing voltage to a first node. The input circuit provides the voltage of the first node to a second node. The reset circuit resets the voltage of the second node. The storage circuit stores a voltage difference between the second node and a second supply voltage terminal. The selection circuit provides a third supply voltage to a third node. The source follower outputs a current corresponding to a voltage between a first electrode and a control electrode via an output terminal. The compensation circuit provides a compensated sensing voltage to a control electrode of the source follower.
