摘要： A power converter may include a first power path having no energy storage and a second power path having substantial energy storage. The first and second power paths have first and second input waveforms that are complementary with respect to a source waveform. The first power path, which may be more efficient than the second path, may transfer as much power as possible from the input to the output. The energy storage enables the second power path to make up the difference between the power available from the source and the power drawn by the first power path, and to make up the difference between the power demanded by a load and the power supplied by the first path.

摘要： A local power converter may include a controller to manipulate the operating point of a local power converter to cause the power point tracking feature of a central power converter to operate at a point determined by the controller. In some embodiments, the controller can manipulate the operating point of the local power converter by alternating between at least two modes. In some other embodiments, the controller can manipulate the operating point of the local power converter to provide a substantially constant slope. In some other embodiments, the controller can maintain a substantially constant impedance ratio. In some other embodiments, the controller enables perturbations from the power point tracking feature of the central power converter to reach the power source.

摘要： A high speed, multiple input restrictive OR circuit with fully differential inputs and output is used in applications in which only one input can be active at a time. N differential voltage inputs are converted into N corresponding differential current signals of unit current values. The current signals corresponding to active complement input signals are summed together, with a compensation current equal to (N−1) current units subtracted from the total. The resulting compensated complement currents together with any active input current form a single differential current that indicates the logic state at the input. This differential current is preferably converted to a buffered output differential voltage in an output stage. For high accuracy applications, a common unit reference current is used to generate both a scaled compensation current and unit input stage source currents.

摘要： An input signal is applied to a ratiometric gain/attenuator circuit. A nulling circuit is arranged to null the input signal with an output from the ratiometric gain/attenuator circuit. The ratiometric gain/attenuator circuit may include a gain stage in series with a ratiometric attenuator. By implementing the attenuator ratiometrically, the gain may be compensated with reference to a ratio of component values. A limiting stage with an absolute reference may precede the gain stage, and a pair of detector cells may arranged at the inputs to the nulling circuit.

摘要： The intercept of a logarithmic amplifier is temperature stabilized by generating a signal having the form H log H where H is a function of temperature such as T/T0. The first H factor is cancelled, thereby generating a correction signal having the form Y log H. The cancellation may be implemented with a transconductance cell having a hyperbolic tangent function. The H log H function may be generated by a pair of junctions biased by one temperature-stable current and one temperature-dependent current. The pair of junctions and the transconductance cell may be coupled together in a translinear loop. A user-accessible terminal may allow adjustment of the correction signal for different operating frequencies.

摘要： D flip-flop structures are provided which respond to a DATA signal and a clock (CLK) signal by generating an output signal whose state during each clock pulse is that of the DATA signal at that pulse's leading edge and whose state between clock pulses is reset to a selected logic value. Accordingly, these flip-flops can function (e.g., monitor events in the DATA signal or generate sequences of trigger pulses) at the clock rate.
