Webthe subthreshold or saturation region with low dynamic offset variation. Simulation results show that when the common-mode voltage sweeps from 1/2V DD to V DD at 1.2 and 0.6 V supply, total offset voltages of the proposed comparator are about 36.4 and 14.6 mV with the fluctu-ation of 0.15 and 0.39 mV without any particular offset cancellation WebJan 1, 2012 · Dynamic Offset Cancellation for PLL-Based Sensor Interfaces. ☆. Time-/frequency-to-digital conversion is gaining in popularity since it benefits from the improved timing resolution in new technologies whereas voltage processing suffers from the reduced supply voltage. Sensor signals however are small compared to other signal processing …

offset cancellation - 英中 – Linguee词典

WebA low-offset dynamic comparator using new dynamic offset cancellation technique is proposed. The technology scaling of MOS transistors enables low voltage and low power which decreases the offset voltage and delay of the comparator. The new technique achieves low offset and low voltage without pre-amplifier. WebPrevious designs employed dynamic offset cancellation tech-niques, such as nested-chopping [1], [5], [7] and autozeroing [4], [8], to reduce temperature errors due to the offset of the CMOS amplifiers used in the readout circuitry. Since the char-acteristics of the bipolar transistors used are not entirely linear, ordeal of civility by john murray cuddihy
