Abstract
An electronic device may include wireless circuitry having an oscillator. The oscillator can include a pair of n-type transistors coupled to a first tail node, a pair of p-type transistors coupled to a second tail node, a load inductor coupled between the pair of n-type transistors and the pair of p-type transistors, a load capacitor coupled between the pair of n-type transistors and the pair of p-type transistors, a tunable capacitor, and a first transformer coupled between the first tail node and the tunable capacitor. The oscillator can further include a second transformer coupled between the second tail node and the tunable capacitor. The tunable capacitor can include multiple differential switchable capacitor circuits.
