Voltage-Controlled Ring Oscillator for Low Phase Noise Application

A design for a voltage-controlled ring oscillator (VCO) is presented. The design allows an implementation of low frequency ring oscillator using relatively small devices and less stage. It is implemented using .18um technology provided by TSMC technology using 3.3V power supply. The VCO topology exhibits a very wide tuning range from few Hz to 368.9 MHz. It also features the rapid voltage swing...

A Low Power Low Phase Noise Lc Voltage- Controlled Oscillator

A low phase noise CMOS complementary cross-coupled LC-tank voltage-controlled oscillator (VCO), implemented with TSMC 0.18μm 1P6M CMOS technology, is presented. Double pair pseudoresistance transistors biased by the tapped center of the inductor are utilized to reduce the DC bias current. The circuit consumes 1.55 mA from a 1.5 V supply voltage which saves up to 52.4% power, compared with the c...

Resistor Controlled Voltage-Mode Eight-Phase Sinusoidal Oscillator Using MOCCIs

A simple scheme is given for the realization of a voltage mode three-output sinusoidal oscillator (VMTOSO). Using this scheme a negative type second generation current conveyor, [CCII(-)]-based VMTOSO is realized. The [CCII(-)]-based VMTOSO is then transformed into a multioutput current conveyor [MOCCII]-based voltage mode eight-phase sinusoidal oscillator (VMEPSO) by replacing all the CCII(-) ...
