Peripheral cells design for low suply current CMOS ASIC

Some new solutions featuring very low current consumption in stand-by mode for the specialized circuit are proposed. The supply current of RC oscillatorn does not exceed 20 μA at 5 V, power on reset circuit consumens less than 3 μA. The input pull-up cell with high immunity to noise coupled by pins capacitances drains no more than 300 nA. These solutions were implemented in the multifonction decoder circuit realized using CMOS 1.2 μm process and 5 V supply voltage.
