ABSTRACT:
A very high speed, high resolution analog to digital converter is detained including a subrange architecture, with the main range A/D including a digital to analog portion for producing an analog signal which can be summed with an amplified input analog signal. The summed analog signal is directed through a unity gain buffer to the subrange analog to digital converter, with the buffer isolating the high input capacitance of the subrange A/D from the summing node. The main range A/D provides a binary coded digital signal which approximates the input analog signal and which defines the most significant bits (MSB) of the digital output. The least significant bits (LSB) are had from the subrange A/D which provides at least one more bit than the number of MSB to provide overlap for forming the combined digital output signal.
