摘要： A successive approximation analog-to-digital converter includes a capacitor array having a plurality of switch capacitors therein with varying weights, each having a common plate connected to a common node and a switched plate. A SAR controller samples an input voltage on said capacitor array in a sampling phase and redistributes the charge stored therein in a conversion phase by selectively increasing the voltage on select capacitors of the capacitor array in accordance with a SAR conversion algorithm. Circuitry controls the sampling of the input voltage by the capacitor array and is responsive to at least one applied bias current. The at least one applied bias current operates at a first level responsive to a first mode of operation of the SAR ADC and operates at a second level responsive to a second mode of operation of the SAR ADC.

摘要： A method for operating an N-bit SAR ADC as a greater than N-bit resolution SAR ADC includes the steps of taking a plurality of samples for each analog value being converted to a digital value by the SAR ADC. A portion of an LSB is added to all but one of the plurality of samples. The plurality of samples are then accumulated and output as a digital value. The digital value has a resolution greater than the N-bit resolution of the SAR ADC.
