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.
