PIPELINED ANALOG TO DIGITAL CONVERTER WITH AT LEAST THREE SAMPLE CHANNELS

A pipelined analog to digital converter wherein at least one stage comprises three or more sample channels. The at least one stage comprises an input sample circuit, a quantization circuit and an amplification circuit. The input sample circuit comprises three or more channels and each cycle one of the three channels samples the received analog signal. The quantization circuit receives the samplesfrom the input sample circuit one cycle after they were generated, such that the quantization circuit receives a sample from one of the three or more channels each cycle, and quantizes each received sample into one or more bits of the digital word for that sample. The amplification circuit receives the samples from the input sample circuit two cycles after they were generated and the bits corresponding to that sample one cycle after they were generated, such that the amplification circuit receives a sample from one of the three or more channels and the corresponding bits from the quantizationcircuit (or an analog sign
