    • PROBLEM TO BE SOLVED: To provide a high resolution, operational-amplifier-less/capacitor-less TD converter that reduces a switching loss and dispenses with statically holding phase information.SOLUTION: The TD converter includes: an oscillation circuit section 1 fed with time domain data; a High counter circuit section 3 for measuring a wave number of an output oscillation waveform of the oscillation circuit section while the time domain data is "High," and a Low counter circuit section 4 for measuring a wave number of the output oscillation waveform of the oscillation circuit section while the time domain data is "Low"; an output signal generation section 5 for generating an output signal from output count values of the High counter circuit section 3 and the Low counter circuit section 4; and a frequency control circuit 2 capable of causing the oscillation circuit section to oscillate continuously and controlling the oscillation frequency.
    • 要解决的问题:提供一种降低开关损耗并省去静态保持相位信息的高分辨率,无运算放大器/无电容器的TD转换器。解决方案:TD转换器包括:馈送时间的振荡电路部分1 域数据; 用于测量时域数据为“高”的振荡电路部分的输出振荡波形的波数的高计数器电路部分3和用于测量输出振荡波形的波数的低计数器电路部分4 振荡电路部分,而时域数据为“低”; 输出信号生成部分5,用于从高计数器电路部分3和低计数器电路部分4的输出计数值产生输出信号; 以及能够使振荡电路部连续振荡并控制振荡频率的频率控制电路2。
