摘要： A voltage-controlled oscillator has a tuned circuit for controlling the oscillation frequency. The tuned circuit has a variable-capacitance element whose capacitance varies in response to a control voltage and a negative capacitance circuit whose impedance frequency characteristics have opposite characteristics to those of a normal capacitance, and which is connected to the variable-capacitance element. The configuration enables increasing the variation ratio corresponding to the control voltage of the combined capacitance composed of the variable-capacitance element and negative capacitance circuit, thereby broadening the oscillation frequency band.

摘要： A signal transmission system has a modulation signal converter 1 that generates a modulation signal using a Manchester code with a duty ratio of 50% in accordance with transmission data; a clock generator 6 that generates a clock with the amount of delay with respect to the rising or falling edge of the modulation signal; and a data detector 5 that generates received data by sampling the modulation signal in synchronization with the clock. Since the modulation signal converter 1 generates the modulation signal by combining the Manchester code with the duty ratio of 50%, its duty ratio is always 50% independently of the transmission data, thereby preventing the DC offset of the modulation signal on the receiving side. Accordingly, it offers an advantage of achieving good communication quality with a simple circuit configuration without producing the DC offset in the modulation signal on the receiving side.
摘要翻译：信号传输系统具有调制信号转换器1，其根据传输数据使用占空比为50％的曼彻斯特码生成调制信号; 时钟发生器6，其产生相对于调制信号的上升沿或下降沿具有延迟量的时钟; 以及数据检测器5，其通过与时钟同步地对调制信号进行采样来生成接收数据。由于调制信号转换器1通过组合占空比为50％的曼彻斯特码来产生调制信号，所以其占空比总是与发送数据无关地为50％，由此防止接收侧的调制信号的DC偏移。相应地，它具有以简单的电路配置实现良好的通信质量而不在接收侧的调制信号中产生DC偏移的优点。
