实践中放置一大一小2个电容是比较常见的做法,比如0.1uF和10uF。 如果对这个参考电压的精度要求比较高,我建议使用额外的参考电压源,比如AS431这种3端稳压源可以提高0.5%或1%的稳压精度。 在实践中,很多时候会忽略参考电压的误差问题,而直接从Vcc取电,用电阻分压的方式获得参考电压。比如下面这种常用的NTC温度检测电路...
Diverse LC filters are formed by combining inductors and capacitors In electronic circuits, the property of capacitors to pass higher-frequency AC currents more smoothly is utilized in a multitude of ways. The most basic form is a circuit that combines a capacitor and a resistor. ...
MEMS variablecapacitorscan be used as tuning elements in several RF systems, such as voltage-controlled oscillators (VCOs), tunable filters, and impedance-matching networks. Their size and RF response significantly affects the performance of the system. Recently, several MEMS variable capacitors have ...
