A 0.25-[micro]m CMOS quad-band GSM RF transceiver using an efficient LO frequency plan

In particular, reducing the number of voltage-controlled oscillators (VCOs) required for local oscillator (LO) frequency generation is very important because the VCO and phase-locked loop (PLL) circuits occupy a relatively large area.
