System and method for converting direct analog samples to compressed digitized samples

A method for converting direct analog samples to compressed digitized samples, the method comprising:

• receiving a plurality of input analog samples from an image processing system, wherein the plurality of input analog samples comprises a plurality of analog media voltages;
• compressing the received plurality of input analog samples in an analog domain to generate compressed analog samples using a plurality of switch capacitor circuitry, wherein the compressed analog samples comprise a plurality of significant analog samples and a plurality of insignificant analog samples;
• converting the plurality of significant analog samples to a plurality of digitized significant bits, and wherein converting the plurality of significant analog samples comprises activating an analog to digital converter for processing the plurality of significant analog samples and power gating the ADC for the plurality of insignificant analog samples;
• and
• multiplexing the plurality of digitized significant bits of the ADC and output of a run length encoder unit to generate compressed digitized samples.
