A cross-coupled cascode voltage controlled oscillator including a variable-frequency tank circuit, first and second cascode-coupled active devices coupled to the tank circuit, and third and fourth cascode-coupled active devices coupled to the tank circuit, the first and second active devices being cross-coupled to the third and fourth active devices. The invention produces lower drain the gate voltages resulting in fewer device failures.
