WebAug 23, 2016 · The voltage equivalence of your ADC code output depends on the full-scale range of the ADC and its resolution. For example, an ACD with a ± 5 V input range and a 10-bit output has: V m a x − V m i n 2 N b i t s = 5 V − ( − 5 V) 2 10 b i t s = 9.765625 m V L S B The units mV/LSB are fairly common when working with ADCs. WebTo overcome such a limitation, a HVOPA and a HVT are proposed in this work to carry out high voltage analog circuit design and data transmission. An experimental prototype is implemented using a typical 0.25 μm 1-poly 3-metal 60V BCD process. The post-layout-extracted simulation results proved the functional correctness of our proposed design.
