The voltage reference circuit is called voltage for current source (VCS). Design/methodology/approach - The circuit concept is discussed. A voltage-controlled oscillator (VCO) and buffer circuit together with VCS circuit are built to prove the concept. Though the VCS circuit employs no array of diode like standard bandgap circuit, it still employs the concept of proportional to absolute temperature (PTAT) and a complement to absolute temperature (CTAT) elements. The integrated VCO, together with VCO core and VCO buffer circuits, are designed for W-CDMA application particularly for the demodulator section. All circuits are built in fT=45 GHz SiGe BiCMOS process. Findings - At 760 MHz the power consumption for core circuit is 0.6 and 3.3 mA for VCO buffer amplifier. The fabricated VCO circuit together with VCO buffer was tested and measured with VCO output of -6 dBm at 760 MHz with variation of 0.1 dBm across -40°C to 85°C. Originality/value - A voltage reference circuit which is derived from PTAT and CTAT current generators is presented. The circuit is capable of providing a constant current across absolute temperature or a current PTAT. 2009-07-17T07:21:32Z 2009-07-17T07:21:32Z 2008 Article Microelectronics International, vol.25 (3), 2008, pages 26-32. 1356-5362 www.emeraldinsight.com/10.1108/13565360810889593 http://hdl.handle.net/123456789/6467 en Emerald Group Publishing Limited
