<P>PROBLEM TO BE SOLVED: To provide systems and methods for converting an analog input signal to a digital output signal. <P>SOLUTION: A system includes a current mode (CM) digital-to-analog converter (DAC) circuit 210 to provide a DAC current. A comparator circuit 250 generates a comparator signal in response to an error signal determined based on the DAC current and an analog input signal. A successive approximation register circuit 270 generates at least one of a DAC-code signal 274 or a digital output signal 272, in response to the comparator signal. The DAC-code signal is used by the CM DAC circuit to control the DAC current. <P>COPYRIGHT: (C)2013,JPO&INPIT |
