Abstract
A programmable analog array (10) comprises an array of configurable cells (11), each cell (11) including analog circuitry (12) and digital circuitry (14). The cells (11) are configured for a particular functional application. The digital circuitry (14) converts an analog signal generated by the analog circuitry (12) into digital control information, which is then used to adjust the analog circuitry (12). Therefore, the analog circuitry (12) and the digital circuitry (14) form a digital feedback loop. The digital feedback loop is established either within a single cell or among neighboring cells. Thus, the digital feedback loop is established without using a global data bus.
