A Current Reuse Wideband LNA with Complementary Noise and Distortion Cancellation for Ultrasound Imaging Applications

This paper presents a current reuse wideband complementary noise and distortion canceling low-noise amplifier (LNA) for high-frequency ultrasound imaging applications. A single-ended current-reuse LNA structure with low-voltage power supply is utilized to achieve low power consumption. The LNA employs a shunt-feedback feedforward noise canceling technique to accomplish both low noise figure (NF) and wideband impedance matching. A complementary CMOS topology is also exploited to cancel the even-order harmonics to enhance the linearity. The LNA is designed for 30-120 MHz high-frequency ultrasound imaging systems, and is implemented in a 180 nm CMOS technology. The LNA achieves a 2 dB NFmin, a 23 dB voltage gain, and a −56 dBc total harmonic distortion (THD) while dissipating 9 mW of power from a 1.3 V power supply.
