摘要： An oscillator includes a resonator, a first and a second p-type transistor, and a first and a second n-type transistor. The resonator has a first terminal and a second terminal. The first p-type transistor is switchably connected to the first terminal while the second p-type transistor is switchably connected to the second terminal. A first drain of the first n-type transistor and the second drain of the second n-type transistor are electrically connected to the first terminal and the second terminal, respectively. The oscillator is capable of operating in an NMOS only mode and in a CMOS mode.

摘要： PROBLEM TO BE SOLVED: To reduce the number of parts of an amplifier circuit for obtaining a sawtooth wave and a triangular wave. SOLUTION: A time-constant capacitor C is connected between an emitter-follower output resistor Ra and a time-constant resistor R to generate Miller effect that seemingly makes the time-constant capacitance C multiplied by an amplification degree (G/0.99-1). A voltage obtained thereof is amplified by an operational amplifier by being multiplied by A=G/0.99-1, and a triangular-wave voltage is obtained. When the charging of the time-constant capacitor C of the NPN transistor emitter follower from an astable multivibrator circuit, which is located in the front stage of the NPN transistor emitter follower circuit, finishes and the discharging starts, a connected diode turns to be in the forward direction. The capacitor C therefore discharges through the collector resister of the transistor not making the amplification in the astable multivibrator, and the latter half part of the voltage waveform latter from the top of the triangular voltage suddenly goes down, resulting to yield a sawtooth wave voltage.

解决方案：时间常数电容器C连接在发射极跟随器输出电阻器Ra和时间常数电阻器R之间以产生似乎使时间常数电容C乘以放大度的米勒效应（G / 0.99 -1）。通过乘以A = G / 0.99-1，通过运算放大器对其获得的电压进行放大，得到三角波电压。当位于NPN晶体管射极跟随器电路前级的非稳态多谐振荡器电路对NPN晶体管射极跟随器的时间常数电容器C进行充电时，开始放电，连接的二极管转为前进方向。因此，电容器C通过不在不稳定的多谐振荡器中进行放大的晶体管的集电极放电，并且从三角形电压的顶部开始的电压波形的后半部分突然下降，导致锯齿波电压。版权所有（C）2008，JPO＆INPIT
