An ultrasonic analog front-end (AFE) interface IC for capacitive micro-machined ultrasound transducer (CMUT) in medical imaging systems using 0.18-µm standard CMOS process is presented in this work. The proposed AFE IC operating at 2.6 MHz is comprised of 15-Vpp high-voltage reconfigurable pulser/switch for transmit mode and low-noise preamplifier followed by a low-power time-gain compensation (TGC) amplifier with accurate programmable gain on receive mode. A total input referred current noise density of 415 fA/√Hz at 2.6 MHz is obtained in the receiver front-end IC while consuming 1.28 mW at 1.5-V supply. The AFE IC occupies 0.086 mm2 of layout area.
