Abstract：
 The special feature lay on that: adopts the novel digital control mutual complementary type MOS capacity-variable diode to build digital control oscillator, therefore reduces the phase noise and stray of the oscillator and raises the frequency modulation precision of the oscillator. Comparing with the existed method, the method raises the function of the CMOS on-chip oscillator effectively, reduces the oscillator power and benefits to reduce the receiver cost and power consumption.
