Abstract: An ultrasound transmission circuit comprises a pulse generating circuit, a feedback circuit and a processing circuit. The feedback circuit outputs a trigger signal according to a first pulse signal arriving at an ultrasound transducer. The processing circuit records a first time point at which the first pulse signal is generated, and records a second time point at which the first pulse signal arrives the ultrasound transducer according to the trigger signal. The processing circuit adjusts a first delay value according to a variance between the first time point and the second time point to generate a second delay value, and drives the pulse generating circuit according to the second delay value to generate a second pulse signal.

Abstract: A voltage protection transceiver is introduced herein. The voltage protection transceiver includes a transmission element and a voltage-driven switch circuit. The voltage-driven switch circuit at least includes a sensing circuit and a protection switch. The voltage-driven switch circuit and the transmission element for transmitting input signals are separated from each other for maintaining integrity of transmission of signals. When a voltage level of the input signal is higher than a predetermined value and being detected by the sensing circuit, the voltage-driven switch circuit is turned on to protect electrical components at an output stage from being damaged or influenced by the high-level input signals. When the voltage level of input signals is lower than the predetermined value, the voltage-driven switch circuit is turned off to reach an output without power loss.
