This letter presents the design and analysis of a novel in-phase-coupled (IPC) Class-C Quadrature Voltage-Controlled Oscillator (QVCO) with tunable phase error. The IPC QVCO employs a novel coupling structure that generates in-phase coupling signal while consuming negligible power itself. IPC scheme...
