Low noise reference circuit of improving frequency variation of ring oscillator |
摘要 |
A low noise reference voltage circuit without using an amplifier inside is capable of transforming a current IPTAT in positive proportion to absolute temperature into a voltage VPTAT in positive proportion to absolute temperature, and outputting it to a ring oscillator. The low noise reference voltage circuit improves a degradation of noise performance compared with a conventional band-gap reference voltage circuit and is in characteristic of low noise and higher PSRR. |
