An apparatus comprises a cross-coupled differential amplifier, an inductive-capacitive (LC) tank circuit, and a low-noise voltage supply. The inductive-capacitive (LC) tank circuit is generally coupled in a feedback path of the cross-coupled differential amplifier. The LC tank circuit generally ...
In a quadrature phase-locked loop (PLL) circuit, two separate inductors are positioned close to each other, where the first inductor provides in-phase oscillation whereas the second inductor provides quadrature oscillation. Together, these two inductors and their corresponding capacitors provide 4 ...

For instance, we showed in previous works the use of LC cells to implement electronic devices such as sinusoidal oscillators [11], phase-locked loops (PLLs) [12] or tunable series-parallel resonators [13]. Within all these applications, the use of LC cells as a temperature sensor is also...

and a total of 7.5 ps peak-to-peak with a bit error rate of 10^(-12).The random and total jitter values for frequencies of 426 MHz and 20 MHz are less than 1.8 ps and 65 ps,respectively.The LC-PLL consumed 27 mW for the core and 73.8 mW in total.The measured results nearly ...
A phase-locked loop(PLL) is an essential and broadly used circuit in these applications.This study presents an application-specific integrated circuit of a low-jitter, low-power LC-tank that is PLL fabricated using 55-nm CMOS technology. It includes a 3 rd-order frequency synthesis loop with...
The clock generator is based on a PLL frequency synthesiser with a low phase noise LC Voltage-controlled oscillatror (VCO). This kind of oscillator achieves the required low jitter specification with a substantial lower power consumption than a conventional ring VCO. In order to save die area,...
