N2 - An ultrasonic receiver front-end interface IC for capacitive micromachined ultrasound transducer in medical imaging systems is presented in this work. The proposed receiver front-end IC is comprised of a low-noise preamplifier providing a transimpedance gain of approximately 103 dBohm, followed by a low-power time-gain-compensation amplifier with accurate programmable gain. An input referred noise current density of 380 fA/VHz is obtained in the front-end IC while consuming 1.28 mW at 1.5-V supply. The proposed IC is designed using 180 nm CMOS process and the overall area is 0.042 mm2.
