RC relaxational oscillator with high supply rejection
A low power RC relaxation oscillator with very low voltage and temperature sensitivities is presented. Supply sensitivity is reduced by using a self-regulation loop that biases the oscillator near its zero-voltage coefficient point. Fabricated in a 65nm CMOS process, the prototype 1.5MHz oscillator …

Ring oscillator based injection locked clock multiplier
This thesis describes a ring-based injection locked clock multiplier (ILCM) designed with the goal of generating a high-frequency and low-jitter clock. Building on prior research done on injection locking, this design uses a reference frequency doubling technique to push the noise bandwidth of the …

Experimental investigation of a coaxial gyrotron oscillator
… a megawatt power level, 140 GHz coaxial gyrotron oscillator. The coaxial gyrotron has the potential to transport very high power electron beams and thus achieve higher microwave output power levels than conventional gyrotrons. A TE2 ,3 coaxial gyrotron was designed to operate at 95 kV, 76 A. This …

Genetic noise in the cyanobacterial circadian oscillator
… environment. Circadian rhythms, driven by oscillators which provide cells with an internal clock that controls the gene expression program, have been observed in a wide range of organisms from cyanobacteria to mammals. To explore the impact of stochastic expression fluctuations on the …

Frequency synthesis using phase-controlled oscillator techniques
The behavior of the phase-controlled oscillator has been the subject of extensive analysis for many years. However, the vast majority of the literature assumes that the phase comparator, or error detector, of the system produces an output proportional to the sine of the phase difference. In recent …

Automatic generation of an LC voltage controlled oscillator
A Voltage Controlled Oscillator (VCO) is used to generate a signal with a frequency that is a function of an input voltage amplitude, and is an integral part of circuits such as phase locked loops, frequency synthesizers, down conversion receivers, and clock generators. A typical design flow for a …

A temperature-compensated RC oscillator using temperature sensor
… a temperature sensor to compensate for an RC oscillator based on FLL (frequency-locked loop), on the same die of the temperature sensor, with the assistance of a frequency counter and a computer. The TCO (temperature-compensated oscillator) and the temperature sensor are presented by Khashaba …

A temperature insensitive low noise RC relaxation oscillator
A 50 kHz temperature insensitive RC relaxation oscillator is presented. A novel RC branch, which has a zero temperature coefficient (ZTC) point in its charging curve, is used so that the period of the oscillator is insensitive to temperature variation. With the absence of current source in the RC …
