A 12b 2MS/s cyclic ADC achieves low power consumption with a single-ended rail-to-rail input signal range of 3.3Vp-p. The proposed voltage reference scheme directly employing power supply voltages implements an offset voltage less than 1mV without well-known calibration and trimming techniques. The prototype ADC in a 0.18mm CMOS technology demonstrates the(More)
Only limited information is available in the research area on the effect of elevated CO2 concentration ([CO2]) and air temperature (Tair) on the fertilizer N uptake by rice. This study was conducted to investigate changes in rice uptake of N derived from fertilizer (NDFF) and soil (NDFS) as well as fertilizer N uptake efficiency (FUE) with elevated [CO2](More)
