Abstract
An oscillator and method for generating a signal are provided. The oscillator comprises an electro-mechanical resonator and a reconfigurable oscillator driver. The reconfigurable oscillator driver starts the oscillator in single-ended mode to avoid latching and transitions the oscillator to differential mode in such a manner as to sustain oscillations therein. The reconfigurable oscillator driver comprises two back-to-back banks of inverters and an adjustable feedback resistor. In single-ended mode, one bank is disabled and the other bank is enabled. To transition to differential mode and improve the quality of the signal, the number of enabled inverters is equalized in both banks.
