Abstract
A method includes providing a first voltage to a first output node during a first time interval, providing a second voltage to the first output node during a second time interval, and averaging the first and second voltages to provide a reference voltage to a second output node. The first voltage includes a proportional-to-absolute-temperature (PTAT) component, a complementary-to-absolute-temperature (CTAT) component, and a first residual offset component. The second voltage includes the PTAT component, the CTAT component, and a second residual offset component. An apparatus includes a discrete-time circuit to provide the first voltage to the first output node during the first time interval and to provide the second voltage to the first output node during the second time interval, and a filter to average the first and second voltages to provide the reference voltage to the second output node.
