Abstract :
An integrated circuit is presented which receives an input IF frequency in the range of 70-300 MHz, and achieves 117 dB of dynamic range in a 200 kHz bandwidth (BW). An automatic-gain-control (AGC) loop is placed around the analog-to-digital converter (ADC). Amplitude-modulation (AM) caused by gain switching is corrected digitally.
