Abstract:
A low-noise, low-power reference voltage circuit can include an operational transconductance amplifier (OTA) with inputs coupled to a temperature-compensated voltage, such as can be provided by source-coupled first and second field-effect transistors (FETs) having different threshold voltages. A capacitive voltage divider can teed back a portion of a reference voltage output by the OTA to the inputs of the OTA to help establish or maintain the temperature-compensated voltage across the inputs of the OTA. A switching network can be used, such as initialize the capacitive voltage divider or other capacitive feedback circuit, such as during power-down cycles, or when resuming powered-on cycles. A switch can interrupt current to the OTA during the power-down cycles to save power. The cycled voltage reference circuit can provide a reference voltage to an ADC reservoir capacitor. Powering down can occur during analog input signal sampling, during successive approximation routine (SAR) conversion, or both.

Claim (Index 26):
The method of  claim 18 , comprising dynamically bandlimiting the generating the reference voltage during the operating cycle of the voltage reference.
