摘要： A method and system of decimating a Pulse Width Modulated (PWM) signal (537) is provided. The method includes computing one or more timestamps (553) of the PWM signal (537), the PWM signal being at a first sample rate (567). The one or more timestamps (553) are computed at a second sample rate (568), which is lower than the first sample rate (567). Thereafter, the method generates a plurality of pre-filter signals (557-n) based on each of the one or more timestamps (553) and a plurality of translation factors (555-n). The plurality of pre-filter signals (557-n) is then filtered at the second sample rate (568) using a plurality of Infinite Impulse Response (IIR) filters (560-n) to generate a plurality of intermediate decimated Pulse Code Modulated (PCM) signals (563). The plurality of intermediate decimated PCM signals (563) is combined to generate a PCM signal (569).

摘要： A pulse width modulation (PWM) generator featuring very high speed and high resolution capability and the ability to generate standard complementary PWM, push-pull PWM, variable offset PWM, multiphase PWM, current limit PWM, current reset PWM, and independent time base PWM while further providing automatic triggering for an analog-to-digital conversion (ADC) module that is precisely timed relative to the PWM signals. Applications include control of a switching power supply that requires very high speed operation to obtain high resolution at high switching frequencies, and the ability to vary the phase relationships among the PWM output signals driving the power supply power components. A single PWM duty cycle register may be used for updating any and/or all PWM generators at once to reduce the workload of a digital processor as compared to updating multiple duty cycle registers.

摘要： In digital-to-analog conversion systems, a method and system for increased effective resolution in an N-bit DAC are provided. Additional resolution may be provided in an N-bit DAC by increasing the number of periods that an N-bit PWM may utilize to generate an output train of pulse widths with a desired duty cycle. An increased resolution bits parameter may correspond to the additional bits necessary to provide the increased resolution. An iterative process by which a desired value is converted into a sequence of N-bit control words may be based on a desired analog value and the increased resolution bits parameter. In addition to higher resolution, most of the output pulse AC energy is concentrated at the N-bit PWM basic frequency and above, allowing for simpler analog filtering of the pulse width modulated signal.
