142 dB /spl Delta//spl Sigma/ ADC with a 100 nV LSB in a 3 V CMOS process
A /spl Delta//spl Sigma/ ADC designed in a 0.6 /spl mu/m CMOS process uses a reference voltage of only 1.0 V to provide a dynamic range of 142 dB and 132 dB in a bandwidth of 100 and 1000 Hz, respectively. The power optimized ADC implemented using a noise cancellation strategy has a noise floor of -168 dB, equivalent to the noise of a 1 k/spl Omega/ resistor. A reference ADC designed without a noise reduction mechanism has a noise floor of -148 dB. The high resolution converter targeted for sensitive instrumentation such as remote seismic monitoring and biomedical devices consumes 22.8 mW from a single 3.0 V supply.
