Abstract
An example digital-to-analog converter (DAC) circuit may comprise a plurality of single-bit DAC elements, an encoder circuit, and a multiplexer circuit. The encoder circuit may be configured to generate a control signal, where a number of asserted bits in the control signal is based at least in part on a digital input signal and an asserted bit pattern of the control signal is based at least in part on a random signal. The multiplexer circuit may be configured to modify the control signal to generate a noise-corrected control signal having a noise-corrected bit pattern. The noise-corrected bit pattern may direct a first asserted bit of the noise-corrected control signal to activate a first single-bit DAC element and a second asserted bit of the noise-corrected control signal to activate a second single-bit DAC element, where the first single-bit DAC element and the second single-bit DAC element having respective errors that at least partially cancel.
