摘要：

This paper describes a temperature insensitive and low-power 315MHz voltage-controlled ring oscillator with successive approximation frequency calibration and temperature feedback compensation. The primary goal is to provide a small form-factor oscillator for using as a crystal replacement in space-constrained mobile devices. The oscillator uses CSMC 0.35 mu m process for design and simulation. It uses a frequency of calibration technology to achieve 1.2MHz/V output frequency offset with power supply voltage of 2.5-5.5V and the supply current is 1.5-2.9mA. Meanwhile, the self-temperature compensation circuit is an innovative compensation circuit structure, and it can compensate different temperature characteristics of VCO. The frequency stability over the temperature range (-30 degrees C to 80 degrees C) is 25ppm/degrees C.
