An analog-digital CMOS semicustom array for high-performance mixed-mode ASICs

A standard-digital-CMOS-process-compatible analog-digital CMOS semicustom array architecture is presented. The array is suitable for high-performance SC circuit design, though, other circuit techniques such as SI and continuous-time analog signal processing are possible. Main cells of an analog standard cells library are presented as well as experimental results of testing some SC systems such as the 5-th order elliptic SC low-pass filter and the 10-bit DAC are discussed.
