This paper presents a high-precision, low temperature coefficient (TC) CMOS bandgap reference for high-performance multi-channel ADC working under wide temperature range. A piecewise curvature compensation technique is proposed to extend its operating temperature range and keep its low temperature coefficient. A ß-compensation technique is used to cancel the PTAT and non-PTAT spread of the output...
Nutrition is one of the most important factors affecting the reproductive performance of animals. Changes in the ovine maternal metabolism during pregnancy are critical to fetal development. To understand the differences in ovine metabolic changes that occur during normal pregnancy, pregnant ewes carrying twin fetuses (n = 8) were selected at 35 days of gestation (dG). All ewes received 100% of National...
This paper proposes a current-mode bandgap reference which employs a novel “coarse” voltage replication to offset the 2nd-order curvature due to base-emitter voltage of the BJT. The coarse replication is based on a process insensitive transcendental equation which regulates the independent CTAT current. The bandgap reference which will be implemented in 0.35µm CMOS process has a low operating current...
