Abstract

A voltage controlled oscillator (VCO), including: at least one second upper voltage rail; at least one second lower voltage rail; a ring of N cascaded inverters, wherein the set of N cascaded inverters are coupled between the at least one second upper voltage rail and the at least one second lower voltage rail; at least one first frequency band select circuit coupled between first upper voltage rail and the at least one second upper voltage rail; at least one second frequency band select circuit coupled between the at least one second lower voltage rail and first lower voltage rail; at least one first VCO frequency control circuit coupled between the first upper voltage rail and the at least one second upper voltage rail; and at least one second VCO frequency control circuit coupled between the at least one second lower voltage rail and the first lower voltage rail.
