Title:
設定可能ワイドチューニングレンジ発振器コア
Document Type and Number:
Japanese Patent JP2012531110
Kind Code:
A
Abstract:
An oscillator includes a resonator, a first and a second p-type transistor, and a first and a second n-type transistor. The resonator has a first terminal and a second terminal. The first p-type transistor is switchably connected to the first terminal while the second p-type transistor is switchably connected to the second terminal. A first drain of the first n-type transistor and the second drain of the second n-type transistor are electrically connected to the first terminal and the second terminal, respectively. The oscillator is capable of operating in an NMOS only mode and in a CMOS mode.
