Abstract
The present invention provides an oscillator including a tapped inductor and a cross-coupled pair. The tapped inductor includes a first terminal, a second terminal, a first tap and a second tap. The cross-coupled pair receives two input signals from the first terminal and the second terminal to generate two output signals to the first tap and the second tap, respectively.
Claims13
An oscillator, comprising:
- a tapped inductor comprising a first terminal, a second terminal, a first tap and a second tap;
- a cross-coupled pair, wherein the cross-coupled pair receives two input signals from the first terminal and the second terminal to generate two output signals to the first tap and the second tap, respectively;
- and
- a capacitor coupled between the first tap and the second tap, wherein a first node of the capacitor is directly connected to the first tap, and a second node of the capacitor is directly connected to the second tap.
