摘要

采用AMIS CMOS 0.7 mum技术设计了用于电容式压力传感器测量的σ - δ调制谐波信号发生器。谐波信号发生器是电容式压力传感器测量复杂测量系统的重要组成部分之一。整个电容测量系统基于带通(BP) σ - δ调制。利用BP σ - δ调制器进行电容式压力传感器测量，谐波信号和数字采样信号的相位化是电容式压力传感器正常工作的主要要求。利用VHDL语言设计了谐波信号发生器。利用谐波信号发生器的数字同步合成在Cadence BuildGates中完成，并在Cadence Silicon Ensemble中实现。

Digital Synchronization Utilizing Harmonic Signal Generator for Capacitive Pressure Sensor Measurement

The harmonic signal generator utilizing sigma-delta modulation for capacitive pressure sensor measurement was designed in AMIS CMOS 0.7 mum technology. Harmonic signal generator is one of the important parts of complex measurement system for capacitive pressure sensor measurement. Whole capacitive measurement system is based on bandpass (BP) Sigma-Delta modulation. Phasing of harmonic signal and digital sampling signal is main requirement for proper function of capacitive pressure sensor measurement utilizing BP Sigma-Delta modulator. Harmonic signal generator was designed using VHDL. Synthesis of digital synchronization utilizing harmonic signal generator was accomplished in Cadence BuildGates and implemented in Cadence Silicon Ensemble.
