Low power wide bandwidth programmable gain CDS amplifier/instrumentation amplifier |
摘要 |
A method and circuitry for implementing programmable gain. More particularly, embodiments of the present invention provide an amplifier circuit which can be used as a CDS-amp or an instrumentation amplifier. Included is a two-stage amplifier, each stage having a few as one transistor. A current source biases one stage of the two-stage amplifier. A load resistor network couples to the two-stage amplifier and is configured to set gain values for the two-stage amplifier.
