| 主权项 | 1. A circuit comprising: a loop filter, wherein the filter comprises an active integrator configured to generate one or more tuning signals; and a voltage-controlled oscillator (VCO) coupled to the loop filter and configured to generate a feedback signal based on the one or more tuning signals, wherein generating the one or more tuning signals is based on the feedback signal, wherein the loop filter is implemented on an integrated chip, and wherein the loop filter does not comprise a capacitor that is external to the integrated chip and used to generate the tuning signals. | ||
