Patent ID: 8587463

Claim:
A method of adaptively and losslessly quantizing an analog signal to a digital signal in an analog-to-digital converter (ADC), wherein the quantizing is based on one or more of an instantaneous amplitude of the analog signal, frequencies of the analog signal, and patterned contents of the analog signal, the method comprising: sampling the analog signal; quantizing the analog signal by a quantizer core, wherein the quantizer core comprises a digital-to-analog converter (DAC), a comparator, and a voltage reference, wherein the quantization is one of efficient lossless and adaptive compression quantization, or a traditional quantization method; determining by an analog compression engine (ACE) whether the sampled analog signal is above or below a defined threshold, wherein the defined threshold includes one or more of an amplitude threshold, a frequency threshold, and patterned adaptive threshold; adaptively manipulating the sampled signal mathematically through at least one of the DAC or voltage reference of the quantizer core; and outputting the digital signal.
