ABSTRACT:
A low-power, high-dynamic range, analog-to-digital (A/D) conversion circuit for converting an analog signal to a digital signal having a controllable amplifier for amplifying the analog log signal received at an input of the amplifier in response to a first control signal and for generating an amplified analog signal, a low dynamic range A/D converter for converting the amplified analog signal to an intermediary digital signal, a controllable bit shift register for scaling the intermediary digital signal in response to a second control signal to generate the digital signal, and a gain control component (AGC) for generating the first control signal to cause the amplified analog signal to be within the dynamic range of the A/D converter and for generating the second control signal to cause the scaling to compensate for the amplification by the amplifier.
