摘要： A frequency divider for converting an n-bit periodic counting stream (each period containing a single zero or one bit, respectively, followed by n-1 one or zero bits) into a 2n-bit counting stream includes a two-input NOR gate or NAND gate, respectively, connected for delivering its output to an n-bit delay device, the NOR or NAND gate further connected for receiving the output of the delay device as feedback at one of its two-input terminals and for receiving the n-bit counting stream at the other of its two-input terminals. The output of the delay device is then a 2n-bit counting stream.
摘要翻译：用于将n位周期性计数流（每个周期包含单个零或一个位，分别为n-1个或零个比特）转换成2n位计数流的分频器包括双输入NOR门或 NAND门分别连接用于将其输出传送到n位延迟器件，NOR或NAND门进一步连接用于接收延迟器件的输出作为其两输入端之一处的反馈，并用于接收n位在其两个输入端子的另一个处计数流。延迟器的输出就是一个2n位计数流。

摘要： The present invention provides a power amplifier operating with a single power supply. The amplifier includes at least one depletion-mode FET for amplifying an ac signal and a negative voltage generator for providing a bias to the FET. Preferably the amplifier further includes a negative voltage regulator to provide a regulated bias to bias the FET for a class A, AB or B operation. The negative generator includes a multivibrator for producing two clock signals and a charge pump which receives the clock signals and produces a negative voltage. Advantageously the negative voltage is provided as a low reference potential to the multivibrator so that the clock signals it produced include a negative voltage period, which enables the charge pump to operate in a power efficient manner.
