摘要: The inter-poly-oxide (IPO) capacitor is one of the main elements in present mixed-mode CMOS process technologies, However, the phenomenon of poly depletion causes a significant change in the measured capacitance with applied voltage, This effect, expressed in terms of the voltage coefficient of capacitance (VCC), can seriously deteriorate analog precision. In this letter, a novel cross-coupled scheme is proposed for the IPO capacitors. The resulting VCC has a very low measured value of 2 ppm/V in a 0.35-mu m standard mixed-mode CMOS process, achieved without any unconventional approaches.
