An all-digital programmable digitally-controlled-oscillator (DCO) for digital wireless applications
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003A programmable digitally controlled oscillator (DCO) core is mapped on an Altera MAX9400 CPLD that can be used for clock recovery circuit of a 2.4-19.2 Kb/sec Gaussian Minimum Shift Keying (GMSK) demodulator. This architecture is suitable for digital wireless transceivers that use different bands for transmit and receive modes, such as GSM and DECT ...

Design of a 3-bit digital control oscillator (DCO) using IMOS varactor tuning
Analog Integrated Circuits and Signal Processing, 2019This paper presents a three-bit digital controlled oscillator (DCO) with three-stage ring topology. The proposed DCO circuit has been realized in TSMC 0.18-μm CMOS technology. DCO circuit has been designed with NAND gate based inverter delay cell for low power consumption and a digitally controlled load element is added at the output node of inverter ...

Proceedings of the 8th Great Lakes Symposium on VLSI (Cat. No.98TB100222), 2002
A 16-bit digitally controlled BiCMOS ring oscillator (DCO) is described. This BiCMOS DCO design provides improved frequency stability under thermal fluctuations. Simulations of a 5-stage DCO using 1 /spl mu/m BiCMOS process parameters achieved controllable frequency range of 90-640 MHz with a linear/quasi-linear range of around 300 MHz.

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2003
A novel digitally controlled oscillator (DCO)-based architecture for frequency synthesis in wireless RF applications is proposed and demonstrated. It deliberately avoids any use of an analog tuning voltage control line. Fine frequency resolution is achieved through high-speed /spl Sigma//spl Delta/ dithering.
