Abstract
An apparatus and method are described to increase the control resolution of an electronic device. In one embodiment, the invention includes a spread pulse modulation module to generate a first set of bits based on a second set of bits that is larger than the first set of bits. The spread pulse modulation module modulates the least significant bit (LSB) of the first set of bits based on information including the LSB modulation period and the LSB modulation duty cycle. The spread pulse modulation module also modulates the least significant bit of the first set of bits so that the least significant bit transitions at least twice from a high value to a low value during the modulation period. This embodiment of the invention also includes a digital-to-analog conversion module to generate an analog input signal to the electronic device based on the first set of bits.
