Abstract :
An area-efficient oscillator topology for dual-band application is presented. The oscillator can be configured to operate in one of two states with distinct oscillation frequencies by reconfiguration of negative transconductance cores that excite the oscillator tank. The oscillator operates at nominal bands of 2.9 GHz and 6.5 GHz. Phase noise performance is presented for both bands. The oscillator is implemented in a 90nm digital CMOS process
