摘要： A multi-channel current regulator includes two or more channels, each channel acting as a current source or sink for a respective load. Each channel regulates its load current so that the load current is proportional to an input voltage supplied to the channel. An operational amplifier is shared between the channels. Each channel is selected in a rotating sequence for connection to the amplifier. As each channel is selected, a two-phase refresh cycle is initiated. During the first phase, the output of the amplifier is charged until it substantially matches the drive voltage of the selected channel. This is followed by the second phase where the output of the amplifier is adjusted until the load current of the selected channel is proportional to a set voltage Vset.

摘要： A circuit structure efficiently multiplies a first and second number. The circuit structure includes multipliers for the pairs of three-bit digits of the first number and three-bit digits of the second number. The multipliers produce six-bit partial products from the pair of three-bit digits of the first and second numbers. Each multiplier includes look-up tables receiving the pair of three-bit digits of the first and second numbers. A summing-tree circuit includes adders arranged in a series of levels, the adders in an initial one of the levels producing partial sums from the six-bit partial products from the multipliers, and for each first and successive second ones of the levels in the series, the adders in the second level producing another plurality of partial sums from the partial sums from the first level. A last one of the levels includes the adder that produces a product of the first and second numbers.

摘要： An integrated circuit contains a current sink that is used to control a channel of varying forward voltage, with a goal of maintaining a minimally sufficient voltage across the current sink. A target voltage for the current sink return is determined, and a switched inductor is used to maintain said voltage. Various target determination schemes are possible, and various enhancements improve startup time, efficiency, and effectiveness.

摘要： An efficient circuit and method for performing radix-3 Discrete Fourier transform (DFT) of a 3*2M size data frame are provided. The data frame is split and fast Fourier transform (FFT) processed as three sub-frames. Radix-3 operations are performed on the FFT processed sub-frames over a number of stages with time shared hardware to compute the DFT of the data-frame. FFT operations are performed on the second and third sub-frames to produce respective sub-transforms. Concurrently with FFT processing of the first sub-frame, butterfly operations are performed on the sub-transforms of the second and third sub-frames. Through the use of time-shared hardware and arranging FFT operations to correspond with radix-3 operations at various stages of processing, the DFT is performed with existing FFT processors while reducing resource requirements and/or reducing DFT transform time over the full-parallel radix-3 implementation.
