Abstract:
Systems and techniques are disclosed for configuring a circuit containing a two-stage amplifier including a first stage containing at least a differential amplifier, a second stage containing at least a transistor, and a sensing circuit configured to provide a gate voltage to a compensation component. The compensation component may be configured to connect the first stage and the second stage and to generate a lead-lag compensation. The compensation component may contain a compensation capacitor and a variable compensation resistive component in series connection with the compensation capacitor.
