摘要：
This paper presents a low power CMOS feedforward automatic gain control (AGC) amplifier based on an integrated received signal strength indicator (RSSI) with process-variation tolerance. Low ripple high dynamic RSSI and fast settling AGC are both achieved with a power-efficient implementation. Raised feedforward AGC amplifier also gets superior linearity to cascade ones due to its high dynamic range detection to input signals. No external component is needed and this design was fabricated in 0.18 μm CMOS process. The measurement results show that RSSI gains at least 60-dB log-linear range and the AGC convergence time is less than 7.8-μs for a 2 MHz signal. It draws 1.1 mA from a 1.5 V supply and obtains −52-dB THD with 0.7 Vpp output voltage.
