发明名称 Switched capacitor current reference
摘要 A current reference using a switched capacitor to produce a substantially temperature invariant output current. Charge subtracted from a relatively large capacitor by a much smaller switched capacitor at a chosen rate substantially determines the output current of the reference. The output current is proportional to the product of a reference voltage, the capacitance of the switched capacitor and the switching frequency.
