An Energy-Replenishing Ultrasound Pulser with 0.25CV(2)f Dynamic Power Consumption
A battery-powered miniature ultrasound (US) imaging system implemented in the form of an endoscopy capsule is a promising diagnostic device [1]. IC technology enables such extreme miniaturization of the US imaging system, and high energy efficiency is one of the most critical features for form-factor reduction and image quality (e.g., frame rate) improvement. Typically, a pulser driving a US transducer is the most power-hungry block in US imaging systems due to the massive parasitic capacitance [2] of the transducer (Fig. 34.4.1).
