Abstract :
State-of-art implementations of pipelined ADC can only realize a multiplying DAC (MDAC) with (2n-1) levels. However, the number of levels needed to optimize the performance may differ from this number. A novel scheme is proposed allowing for realization of an arbitrary number of MDAC levels, while allowing for 1 bit of digital redundancy and digital error correction without any overhead.
