摘要： In a control circuit and method for a high efficiency and low EMI switching amplifier, an input signal is compared with a reference signal to generate a comparison signal, and a control signal is generated in response to the comparison signal for a driver to generate an output signal. The output signal is fed back to control the slope of the reference signal in association with an initial level set for the reference signal to provide a minimum on-time period for the output signal. Alternatively, a reference value is provided to compare with the reference signal for setting a minimum on-time period for the output signal.

摘要： A programmable clock generator, which is used in dynamic-voltage-and-frequency-scaling (DVFS) operated in Sub- and Near-Threshold region. The programmable clock generator includes first pulse generating unit and a pulse multiplier. A first counter is configured to generate a first counting signal, so as to control the phase detector comparing the phase difference between a first pulse signal and a second pulse signal. A first control signal is transmitted by a control unit in accordance with a phase difference signal, and the phase of the second pulse signal is adjusted by a lock-in delay unit, so that a predetermined phase is generated between the first pulse signal and the second pulse signal. The PVT variation may be compensated by the programmable clock generator during the sub threshold region. Therefore, the period of reference clock is in the locking range of lock-in delay line.
