A single stage voltage controlled ring oscillator includes a trans-admittance voltage-to-current circuit coupled to a trans-impedance voltage-to-current circuit. The output of the trans-impedance circuit is connected to the input of the trans-admittance circuit. The trans-admittance and trans-...
The design utilized in the evaluation is a three-stage RO, as shown in Fig. 1a. An enable input activates or deactivates the oscillator, and the response is output by a toggle flip flop. It can be compactly fitted in a single Xilinx Artix-7 slice. The ROs are placed and routed consis...
often thought to be a “square wave” oscillator, at high speeds the waveforms in a three-stage ring are more nearly sinusoidal. If we idealize the waveforms to be sinusoidal with equal delay in each stage, then, the voltage waveforms at each phase can be ...
We passively generate picosecond6.5nJoptical pulses directly from a single-stage oscillator using carbon nanotube mode locker. The mode locker immunized to the high optical power induced damage employs the evanescent field interaction of propagating light with the nanotubes. The mode locker endures the ...
A SET-Hardened Complementary Differential Cell (SET-H CDC) for differential ring VCO has been proposed for radiation environment. The performance of the proposed delay cell has been compared with the existing radiation-hardened topologies using a 3-stage DR-VCO. The proposed delay cell shows improv...
In this work, a performance comparison of extended single-ended and differential CMOS ring oscillators is presented. The proposal is characterized by compared these two types of oscillators with the same center frequency (fc = 5.28 GHz) and the same number of stage (N = 3).We ...
The two ends of the capillary tube are then sealed, and the capillary tube is put onto a motorized micro- scope stage. A CCD camera is used to record the fluorescence images of the encapsulated cells in step 3. A single layer of droplets is formed in the capillary tube, and the ...

as evident from the distinctive peaks its Fourier transforms in Fig.2C. The oscillations were consistent with the eight-step ring oscillator in the pixel TDC50,57. In contrast, the Fourier transform of the photon probability density function of the corrected data was uniformly distributed. This ...
Microwave photon counters offer an alternative to voltage amplification at the millikelvin stage, but require a more involved pulse sequence and suffer from backaction arising from the creation of quasiparticles and their tunnelling. Qubit readout can also be achieved without a parametric amplifier by ...
