Abstract
A digital-to-analog converter (DAC) for converting a digital signal to an analog signal includes a first thermometer decoder and a second thermometer decoder. The first thermometer decoder is configured to decode most-significant bits (MSBs) of the digital signal to generate a first thermometer code. The second thermometer decoder is configured to decode middle bits of the digital signal to generate a second thermometer code. The DAC further includes a plurality of macro cells with each controlled by one bit of the first thermometer code. The plurality of macro cells is configured to provide a first analog signal according to the first thermometer code. The DAC further includes a macro cell configured to provide a second analog signal according to the second thermometer code. The macro cell is further configured to provide a third analog signal according to least-significant bits (LSBs) of the digital signal.
