  • Abstract
    A CMOS low noise amplifier with two automatic gain control loops is presented. Automatic gain control is performed by the use of linearized MOS resistive circuits as voltage controlled resistors. By the use of parasitic lateral bipolar transistors in the input stage, the equivalent input noise is 14nV/¿Hz and free from 1/f noise in the voiceband. Integrated in a 2 ¿m CMOS process the circuit has an active area of 0,8 mm2.
