영문 초록

There is an increasing interest in high-performance A/D(Analog-to-Digital) converters for use in integrated analog and digi l mixed processing systems. Pipeline A/D converter architectures coupled with BiCMOS process technology have the potential for realizing monolithic high-speed and high-accuracy A/D converters. In this paper, the design of 12bit pipeline BiCMOS A/D converter presented. A BiCMOS operational amplifier and comparator suitable for use in the pipeline A/D converter. Test/simulation results of the circuit blocks and the converter system are presented. The main features is low distortion track-and-hold with 0-300MHz input bandwidth, and a proprietary 12bit multi-stage quantizer. Measured value is DNL = ±0.3LSB, INL= ±0.52LSB, SNR=66dBFS and SFDR=74dBc at Fin=24.5MHz. Also Fabricated on 0.8um BiCMOS process.
