摘要：
A periodically resetting integration angle demodulation device and a method using the same is disclosed, which uses a waveform multiplier and a periodically resetting integrator to modulate a continuous-time angle modulation signal into a discrete-time signal. The waveform multiplier multiplies the continuous-time angle modulation signal by a square wave signal whose frequency is integer times a carrier frequency, and then transmits the continuous-time angle modulation signal to a periodically resetting integrated circuit. The periodically resetting integrated circuit performs integration during a carrier period to generate a discrete-time angle modulation output signal. The present invention can greatly reduce the difficulty for designing an optical sensing system in the front end without limiting a modulation depth. Besides, the present invention achieves a small volume, high speed, high sensitivity, high reliability, high performance and high condition-adapting properties.
摘要（中）：
公开了周期性复位积分角解调装置及其使用方法，其使用波形乘法器和周期性复位积分器将连续时间角调制信号调制成离散时间信号。 波形乘法器将连续时间角调制信号乘以频率为载波频率的整数倍的方波信号，然后将连续时间角调制信号发送到周期性复位集成电路。 周期复位集成电路在载波周期期间执行积分以产生离散时间角调制输出信号。 本发明可以大大降低在前端设计光学感测系统的难度，而不会限制调制深度。 此外，本发明实现了小体积，高速度，高灵敏度，高可靠性，高性能和高条件适应性能。
