Hello everyone, I found a charge pump topology as shown below. The control voltage of VCO is provided by the right-hand-side branch, instead of the left-hand-side. Have you seen this circuitry before? What is it called? I want to do some research on this. Furthermore, I think the capacitor C1 still affects the bandwidth of the PLL, even though it is not in the loop directly. Is that right?
Thanks, Yutao Liu
