本文所介绍的数字温度计,是根据晶体二极管正向电阻,通过利用电压控制振荡器(VCO)使其转变成相应频率的原理而制成的。事实表明,利用稳定和灵敏的 VCO,把二极管正向电阻转变成频率信号是容易的,以便能
The digital thermometer described in this article is based on the principle of forward resistance of a crystal diode by using a voltage controlled oscillator (VCO) to convert it to the corresponding frequency. It turns out that using a stable and sensitive VCO, it is easy to convert the diode forward resistance into a frequency signal so that
