In the first use case, a 5-stage ring oscillator
is described using PAElib and implemented with inverters from the 4000 series.
The circuit under test is a voltage-controlled oscillator (VCO) based on a ring oscillator
In general, there are various methods available to reduce the output noise of a ring oscillator
. Some of these methods are intended to lower the effect of a specific noise source while others improve the overall noise characteristics of the circuits.
Current starved voltage controlled oscillator (CSVCO), configured using a CMOS-based ring oscillator
, can be a good choice for clock generator circuit since it offers certain advantages like low power consumption, improved tuning range, simple architecture, low area and ease of integration (Saw and Nath 2015; Zhang and Apsel 2009).
Finally, for the first time, ring oscillator
circuits were reported based on stacked silicon nanowire FETs, including dual work function metal gates for threshold voltage control.
The sensor resistance variation changes the bias current of the ring oscillator
, and hence the frequency of its output.
To overcome this method using the multi feedback ring oscillator
Using a multi-path gated ring oscillator
at this work has demonstrated first- order noise shaping characters.
Though 3-stage ring oscillator
cannot produce quadrature outputs like 2-stage or 4-stage RO, it is faster than its 4-stage counterpart.
The most basic ring oscillator
is simply a chain of single ended digital inverters, with the output of the last stage fed back to the input of the first stage.
The CML divider can be modeled as an injection-locked ring oscillator
with a differential input signal applied to the CML input stage .
Using this process, the researchers built three kinds of circuits to test the nanocrystals performance for circuit applications: an inverter, an amplifier and a ring oscillator
