摘要
用于电池供电的手持式多媒体终端的混合信号系统lsi中嵌入的视频adc必须在0.9-1.5 V电源下工作,以降低系统功耗。通过将双极晶体管的高跨导性和良好的匹配性与MOS开关电容(SC)电路的电路灵活性相结合,1.5 V BiCMOS视频ADC显示模拟BiCMOS即使在1.5 V也具有比CMOS更高的性能。
Video ADCs embedded in mixed-signal system LSIs for battery-operated, hand-held multimedia terminals must operate at 0.9-1.5 V supply to reduce system power. By combining the high transconductance and good matching of bipolar transistors with the circuit flexibility of MOS switched capacitor (SC) circuits, a 1.5 V BiCMOS video ADC shows analog BiCMOS has potentially higher performance than CMOS even at 1.5 V.
