A current reuse voltage controlled oscillator with improved differential output is disclosed. In an exemplary embodiment, an apparatus includes a PMOS transistor and an NMOS transistor coupled together for current reuse and configured to provide differential oscillator outputs. The apparatus also includes a common mode rejection (CMR) circuit coupled between the PMOS and the NMOS transistors, the CMR circuit includes an inductor having a least one tap that can be selectively coupled to a ground to reduce common mode signals at the differential oscillator outputs. |
