Abstract
An analytical output noise voltage model of an ultra low noise amplifier for high impedance ultrasonic transducers is presented. Operational amplifier with low input bias current is needed to avoid using compensation resistance that considerably increases the noise at the input of the operational amplifier. The proposed analytical model, including the ultrasonic transducer, provides a useful tool to design, compare and select component values.
