Abstract
A time-interleaved current-based digital-to-analog converter (current DAC) cell includes first input circuitry configured to receive a digital input signal, a first biasing voltage, a first clock, and a second clock. The first clock and the second clock having a phase offset from one another and having a common period. The current DAC also includes a first gate configured to, responsive to an 'ON' state of the first clock, pass the digital input signal to a second gate, the second gate being configured to, responsive to an ‘OFF’ state of the second clock, output a first DAC cell activation signal. The current DAC further includes first output circuitry configured to, responsive to the first DAC cell activation signal, output a first analog current signal based on (i) the digital input signal and (ii) the first biasing voltage.
