Patent ID: 7889010

Claim:
A compensation circuit comprising: a first transconductance amplifier having an inverse input, a non-inverse input and an output; a first resistor having one terminal coupled to the output of the first transconductance amplifier; a capacitor connected with the first resistor in series, one terminal of the capacitor coupled to the inverse input of the first transconductance amplifier; a second resistor connected between the first resistor and the capacitor in series; a second transconductance amplifier having an inverse input, a non-inverse input and an output, the inverse input of the second transconductance amplifier coupled to the output of the second transconductance amplifier, the output of the second transconductance amplifier coupled to an intermediate node between the first resistor and the second resistor, and the non-inverse input of the second transconductance amplifier coupled to an intermediate node between the capacitor and the second resistor.
