ABSTRACT:
A voltage controlled oscillator comprising first and second differential delay cells. The first differential delay cell has a first control voltage input terminal. The second differential delay cell is coupled to the first differential delay cell in a loop and has a second control voltage input terminal. The second voltage input terminal is disconnected from the first voltage control input terminal. The first voltage control input terminal receives a first voltage signal, and the second voltage control input terminal receives a second voltage signal different from the first voltage signal.
