An uniplanar capacitance sensor is a core device of high-precision instrument applied to measure wood moisture content, permittivity, etc. In nature, it is a special case of a capacitance sensor of unspecific form. This paper describes the numerical solution to a mathematical model of uniplanar capacitance sensor. An uniplanar capacitance sensor with specific size was taken as an example in this study,...
Performance of analog integrated circuits is highly sensitive to layout parasitics. This paper presents an improved template-based algorithm that automatically conducts performance-constrained parasitic-aware retargeting and optimization of analog layouts. In order to achieve desired circuit performance, performance sensitivities with respect to layout parasitics are first determined. Then the algorithm...
Performance of analog circuits is highly sensitive to layout parasitics. This paper presents an improved algorithm that automatically conducts performance-constrained parasitic-aware retargeting and optimization of analog layouts. In order to meet the desired circuit specification, performance sensitivities with respect to layout parasitics are first determined. Then the algorithm applies sensitivity-based...
A 15 b power-efficient pipeline A/D converter using capacitance-coupling non-slewing amplifiers is presented. A modified 1.5b/stage transfer curve combined with the non-slewing amplifier is useful for the error corrections of incomplete settling error. The relationship between the input signal and the incomplete settling errors can be linearized and the errors can be corrected in digital domain with...
