Wireless communication devices including cordless phones and modern digital cellular systems (DCSs) use portable transceiver systems. The frequency synthesis of this type of transceiver system is done using a phase-locked loop oscillator. Traditional on-chip implementation of a complete phase-locked loop using a ring type voltage controlled oscillator contributes higher noise at the output. An alternative architecture, phase-locked loop (PLL) with wide loop-bandwidth, is proposed in this research to suppress the noise from the traditional ring oscillator. The proposed PLL is amendable to on-chip integration as well as commercially suitable for a Digital Enhancement Cordless Telephone (DECT) system which needs flexible …
