Programmable logarithmic gain adjustment for open-loop amplifiers |
摘要 |
Transconductance-based variable gain amplifiers amplify an input voltage by converting the voltage difference to a current and then amplifying the result. At least one resistor network is adjusted depending on the magnitude of the input voltage difference and the output desired. A network of MOS transistor switches with a small footprint adjusts the resistance of the input voltage circuit in a way to insure consistent resistance and low stray capacitance.
