摘要： An iterative decoder comprising a transconductance amplifier, a sampler, a Min-Sum decoder, and an early determination module is provided. The transconductance amplifier outputs a current proportional to the voltage of the coded bit stream. The sampler converts the amplified current into a plurality of currents and stores the sampled currents in a plurality of buffers. The Min-Sum decoder receives parallel currents, wherein currents represent the message of each variable node. The Min-Sum decoder exchanges the message of variable nodes and check nodes iteratively and outputs a set of decode codewords according to the possibilities. The early terminating module stops the iterative decoding when the decoded codeword converged.

摘要： An exponential charge pump uses a number of identical or similar charging stages, each having a first and second capacitor. During a first clock phase, the first capacitor of each stage is charged by the second capacitor of the preceding stage, and, during a complementary second clock phase, the positive plate of the first capacitor of each stage is pushed to an increased voltage by the first capacitor of the preceding stage and charges the second capacitor of the next stage to the increased voltage at the same time. A similar mechanism occurs to the second capacitors in each stage, but with complementary timing. The increased voltage of the first capacitor of the last stage is pumped to an output capacitor during the second clock phase, and the increased voltage of the second capacitor of the last stage is pumped to an output capacitor during the first clock phase.

摘要： A method and apparatus are disclosed for single-inductor multiple-output switching converter design. With the proposed freewheel switching control, this converter operates in a pseudo-continuous conduction mode (PCCM) and is capable of handling large load currents with a much smaller current ripple and peak inductor current, while retaining low cross regulation. It can also work in discontinuous conduction mode (DCM) for high efficiency at light loads. This design can be applied to have single or multiple outputs and for different types of DC-DC conversions.
