摘要： A method and an apparatus for evaluating weighting of elements of a DAC and a SAR ADC using the same are provided. An equivalent weighting of each composed element is obtained by adding a reference element with a reference weighting, an auxiliary DAC, and a search circuit into the SAR ADC, and the equivalent weighting is represented by the reference weighting. The SAR ADC can calculate and then obtain a correct digital output by using the calibrated equivalent weighting and the successive approximation result of each input signal. The present disclosure prevents the necessity of matching each composed element of the DAC in the SAR ADC.

摘要： A programmable/tunable active low-pass filter at least has the resistors, capacitors and shunt control means. It uses the resistor ladder that is structured with various fixed resistors to implement the shunt control means. The cut-off frequency of a filter is associated with the time constant, which is determined by equivalent resistance and equivalent capacitance value in the filter circuit; therefore, the filter of the present invention allowed users to fine tune the cut-off frequency linearly through the shunt control means when the variation of the environment or process parameters of manufacture cause the cut-off frequency drift, thus, the cut-off frequency can be kept in a constant value. The present invention also provides a means for programming the cut-off frequency to a desirous frequency value dependent upon the conditions of application within a big range. Thus, it can be used in many purposes widely with the same filter circuit.

The voltage regulator circuit has a voltage regulator, a current sensing and comparing circuit, a capacitive load circuit, and a control circuit. The voltage regulator generates an output current in response to a control signal to provide the output voltage.
