Abstract

In this paper, we examine Voltage Controlled Oscillator (VCO) design techniques to be used in different transmitter applications. These transmitters, with their unique specifications such as fast oscillation start-up, fast locking or proper capacitor bank design, require different VCO design considerations. We first look at a fast on-off LC-VCO used to realize OOK IR-UWB transmitter. It is implemented in 0.18μm CMOS process and achieves 2Mbps at 236μW power consumption. Next, we examine injection locking LC-VCO employed to achieve efficient QPSK/O- QPSKB modulation. Through proper capacitor bank design, an EVM of 6.4% has been demonstrated at data rate of 50Mbps with the low reported energy efficiency of 118pJ/bit. The area consumption is only 0.28mm² in 0.18μm CMOS process.
