Abstract
F1exible and wearable devices are of great demand with the developing of the sensors and IoT (internet of the things). The power consumption and volume of the devices need to be reduced in corresponding applications. To meet these requirements, the authors developed and fabricated a low power and high sensitivity analog front-end (AFE) for the ultrasonic imaging. The AFE, including a low noise amplifier (LNA), a 3rd order Butterworth low pass filter (LPF) and a variable gain amplifier (VGA), is fabricated in GF65 nm process. The measurement results indicate 52 dB gain in 10 MHz bandwidth with 16 mW power consumption. An also, the measurement result of the LNA also shows 1nV/$\sqrt{}$Hz input referred noise.
