Abstract
Embodiments described herein provide circuitry for reducing input distortion at a buffer due to large signal swings. The circuitry includes an analog-to-digital converter (ADC), a first buffer, a low pass filter, and a second buffer. The ADC is configured to convert an analog input to a digital output. The first buffer is coupled to an input node of the ADC and the low pass filter is coupled to an output of a driving circuit and an input to the first buffer. The second buffer placed in proximity to the first buffer. An input of the second buffer is connected to an output of the driving circuit and an output of the second buffer is connected to a feedback component of the driving circuit.
