Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...

While graphene is already known as an efficient two-dimensional crystal, it can also work alongside two other nanomaterials to improve electronics, suggests new research found at the University of ...

where f O is the oscillation frequency.With a suitable choice of the valuesof inductors and capacitors, the circuitcan oscillate at frequencies as high as10 MHz. The output clock’s duty cycle ...

Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...
