摘要
An oscillator is provided with an oscillator circuit having tank circuit terminals for coupling to a tank circuit. A microelectromechanical system (MEMS) resonator serves as a tank circuit. The MEMS resonator is coupled to the oscillator circuit using a transformer with a primary coil coupled to the oscillator tank circuit terminals and a secondary coil coupled to the MEMS resonator terminals, wherein the transformer has a turns ratio of N:1 and N is greater than 1.
