We present the design of Analog front end (AFE) low noise pre-amplifier implemented in a high voltage 0.18-μm CMOS technology for a three dimensional ultrasound bio microscope (3D UBM) application. The fabricated chip has 4X16 pre-amplifiers implemented to interface a 2-D array of high frequency capacitive micro-machined ultrasound transducers (CMUT). Core(More)
