Successive approximation analog-to-digital conversion |
摘要 |
Examples of systems and methods are provided for converting an analog input signal to a digital output signal. A system may include a current mode (CM) digital-to-analog converter (DAC) circuit to provide a DAC current. A comparator circuit may be configured to generate a comparator signal in response to an error signal determined based on the DAC current and the analog input signal. A successive approximation register circuit may be configured to generate at least one of a DAC-code signal or the digital output signal, in response to the comparator signal. The DAC-code signal may be used by the CM DAC circuit to control the DAC current.
