Photo-Controlled Oscillator Based on DUBAT
基于双基区晶体管结构的光控振荡器

A novel photo-controlled oscillator (PCO) without inductances is constructed wi th photoelectric diode and DUBAT (dual base trasistor).Simulation based on the equivalent circuit is run and the operating mechanism is analyzed.This PCO can realize the analog-digital transformation from photo to frequency signal as it 's photo intensity and frequency signal are in direct proportion.The novel PCO is a promising option for combination of PCO with functional circuits on a singl e silicon chip because of the simplicity of the structure of DUBAT,the much chea per cost,the facility of fabrication and the compatibility of silicon technology .
