对VCO内核而言，制作一个锯齿波最简单的方法就是“汇合”控制电压。
The simplest way for a VCO core to make a sawtooth wave is to "integrate" the control voltage.
在相同电压及频率下，方波信号激励下的输出灵敏度最大，其次为正弦波，锯齿波最小。
With the same voltage and frequency, bar signal has the highest sensitivity and next the sine, the least sawtooth.
因而产生输出锯齿波，具有一个端点由固定电压源确定，和另一个端点根据定时和开关电容的电容比。
An output sawtooth thereby is produced having one endpoint determined by a fixed voltage source and the other endpoint in accord with the capacitance ratio of the timing and switched capacitors.
