Programmable analog array and method for configuring the same

A programmable analog array, comprising:

• an array of cells, wherein a first cell in the array of cells includes:
• analog circuitry;
• a digital storage element which stores cell configuration data for a plurality of circuit functions;
• a switch control circuit which periodically and sequentially configures the analog circuitry to realize each circuit function of the plurality of circuit functions in accordance with the cell configuration data stored in the digital storage element;
• and
• an analog storage element which stores an analog signal generated by the analog circuitry;
• an interconnection network coupled to the array of cells, wherein the interconnection network allows an interconnection of the first cell in the array of cells with a second cell in the array of cells;
• and
• an access circuit which selectively accesses the first cell in the array of cells, transmits the cell configuration data to the first cell, and transmits interconnection data to the interconnection network.

A method for configuring a programmable analog array, comprising the steps of:

• storing cell configuration data for a plurality of circuit functions in a digital storage element of a first cell in the programmable analog array;
• transmitting a clock signal to the first cell;
• configuring analog circuitry in the first cell to realize a first circuit function of the plurality of circuit functions for a first time interval;
• and
• configuring the analog circuitry in the first cell to realize a second circuit function of the plurality of circuit functions for a second time interval.
