Abstract: An infinite impulse response filter includes a plurality of lower order filter stages and a random number generator circuit. The plurality of lower order filter stages include a first filter stage coupled to a second filter stage. The random number generator circuit includes a first output coupled to the first filter stage and a second output coupled to the second filter stage. The random number generator circuit is configured to generate the same random value at both the first output and the second output. The infinite impulse response filter is an nth-order filter. The respective order of each of the lower order filter stages is less than n.

Abstract: A method of filtering includes generating a random value by a random number generator circuit, filtering a first signal by a first filter to form a filtered first signal, dithering the filtered first signal using the random value to form a dithered first signal, filtering a second signal by a second filter to form a filtered second signal, and dithering the filtered second signal using the random value to form a dithered second signal.

Abstract: A level shifting circuit has an input configured to receive an input signal, wherein the input signal has symmetrical maximum and minimum voltages. The level shifting circuit further includes an output configured to provide an output signal, wherein the output signal has asymmetrical maximum and minimum voltages. The output signal is generated in response to the input signal. The output signal is applied to drive a gate terminal of a SiC MOSFET.
