Abstract
A device comprises a voltage limiter, two capacitors, a resistor, and a voltage follower buffer. The voltage limiter has a first input coupled to a reference voltage rail, a second input coupled to a supply voltage rail, and two voltage limiter outputs. The first capacitor is coupled between a device output and the first voltage limiter output, and the resistor is coupled between the first and second voltage limiter outputs. The voltage follower buffer has an input coupled to the first voltage limiter output and a voltage follower buffer output. The second capacitor is coupled between a device input and the voltage follower buffer output. In some implementations, a resistance of the resistor is greater than a capacitance of the first capacitor. In some implementations, a third capacitor is coupled between the device input and the device output.
