Patent ID: 8810324

Claim:
An oscillating device, comprising: a driving module, used for producing a first driving voltage and a second driving voltage; and an oscillating module, coupled to said driving module, having a first symmetric load circuit, a second symmetric load circuit, and a bias circuit, said first symmetric load circuit and said second symmetric load circuit producing a bias according to said first driving voltage, said bias circuit producing a bias current according to said second driving voltage, and said oscillating module producing an oscillating signal according to said first driving voltage and said bias current; where said bias current is proportional to said bias, said driving module comprises a driving circuit and a converting circuit, said driving circuit produces a control current according to said bias of said first symmetric load circuit, said converting circuit is coupled to said driving circuit for converting said control current to said first driving voltage and said second driving voltage, and transmitting said first driving voltage and said second driving voltage to said oscillating module.
