A 12-bit Interleaved OpAmp-Sharing Pipeline ADC for Extreme Environment Applications

摘要：

This paper presents a 12-bit 5MS/s pipeline analogto-digital converter implemented in a 0.5μm CMOS technology for aerospace extreme environment applications with cryogenic and radiation tolerant capability. It is capable of working under ultra-wide temperature range from -180C to +120℃ and at ultra low temperature of -230℃. To achieve higher sampling rate and lower power, time-interleaved architecture and operational amplifiers sharing technique are used. The cryogenic ADC chip consumes only 30.4niYV at -230℃ from a 3.3V supply voltage. Experimental results show that the proposed ADC can operate under aerospace extreme environment with low power and good robustness.
