Title: Voltage-controlled oscillator
Inventor: WILSON DAVID
IPC: H03B5/12
Filed: 2006-09-21
Abstract: A voltage controlled oscillator comprises first and second voltage controlled oscillator cores for generating I and Q quadrature components respectively. Each of the voltage controlled oscillator cores comprises an inductor. A connecting member is electrically coupled to each of said inductors, thereby forcing the same common mode level in the I and Q core of the VCO.
