High-frequency low-voltage multiphase voltage-controlled oscillator |
摘要 |
A voltage controlled oscillator is provided comprising a plurality of delay elements serially connected to form a ring and each element within the plurality of elements includes an input and output. The voltage controlled oscillator also includes a set of control elements where each control element within the set of control elements has an input connected to an input of a delay element within the set of delay elements and an output connected to an output of a different delay element within the plurality of delay elements. A control voltage is selectively applied to control elements within the set of control elements to vary the oscillating frequency and phase distribution in proportion to the control voltage.
