本文介绍了一种低功耗BiCMOS A/D转换器,它采用“差分电压子转换器”,直接将互补模拟输入的电压差转换为数字码。这种转换技术减少了A/D转换器中的功耗和信号延迟。还新开发了几种电路技术,以实现单5 V电源的高精度转换。该10位A/D转换器采用0.8 /spl μ/mBiCMOS工艺制造,工作频率为50 MS/s,功率为500 mW。
This paper describes a low-power BiCMOS A/D converter using a "differential voltage subconverter", which directly converts a voltage difference of complementary analog inputs to a digital code. This conversion technique reduces power consumption and signal delay in the A/D converter. Several circuit techniques have also been newly developed to achieve high-accuracy conversion with single 5 V power supply. The 10-bit A/D converter is fabricated in a 0.8 /spl mu/m BiCMOS process and it operates at 50 MS/s with 500 mW.
