在电压比较器的设计中,往往要求锯齿波发生器具有良好的线性而且只有几毫伏的放电电平。图中所示电路可以达到这些要求。运算放大器A_1连同R_1=R_2=R_3=R_4作为电流源,电容器C作共负载。当C的电压
In voltage comparator designs, it is often required that the sawtooth generator have good linearity and discharge levels of only a few millivolts. The circuit shown in the figure can meet these requirements. Operational amplifier A_1 together with R_1 = R_2 = R_3 = R_4 as the current source, capacitor C for a total load. When C’s voltage
