A characterization methodology to model interconnect capacitance for accurate circuit simulation is presented. The method utilizes a simple measurement scheme to measure inter-layer capacitances. The measured data is then used to tune a layout tool for accurate interconnect parasitic extraction. Results show good fit between simulated and measured ring oscillator speeds for a production 0.5μm, ...

The reset noise sampling feedforward (RNSF) technique is proposed in this paper to reduce the floor of readout circuit for micro-electromechanically systems (MEMS) capacitive accelerometer. Because technology-imposed size restriction on sensing element, capacitance and variation are reduced femto-farad level. As a result, from parasitic capacitance, which pico-farad level, becomes significant. ...

A new method for the automated measurement of the hysteresis of the temperature-compensated inductance-to-frequency converter with a single quartz crystal is proposed. The new idea behind this method is a converter with two programmable analog switches enabling the automated measurement of the converter hysteresis, as well as the temperature compensation of the quartz crystal and any other circ...

Recent studies in humans have suggested sex differences in venous compliance of the lower limb, with lower compliance in women. Capillary fluid filtration could, however, be a confounder in the evaluation of venous compliance. The venous capacitance and capillary filtration response in the calves of 12 women (23.2 +/- 0.5 years) and 16 men (22.9 +/- 0.5 years) were studied during 8 min lower bo...

Biomass provides 10% of the global energy supply and electricity generation from biomass and waste is expected to increase by a factor of 4 by 2030. Currently efficiency of biomass power generation is poor and IEA targets improvements from 18% to 25% by 2030 [1]. Such increases in efficiency will require significant new technology and accurate real-time measurement of the flow of these highly v...

In this paper we present an electronic circuit for position or capacitance estimation of MEMS electrostatic actuators based on a switched capacitor technique. The circuit uses a capacitive divider configuration composed by a fixed capacitor and the variable capacitance of the electrostatic actuator for generating a signal that is a function of the input voltage and capacitive ratio. The propose...

Architecture and properties of the virtual probes created by the analog modules of the IEEE Std 1149.4 test bus are presented. Capabilities of the bus co-operated with the CIM 97 Multidiatest Measurement System in the area of the analog signal were investigated on the examples of the resistance, capacitance and inductance measurement. Application of the bus, when access to analog nodes of the c...

The paper is focused on identification and measurement of the main parameters of the stacked supercapacitors (SC). The volt-ampere method was used to measure the charge/discharge characteristic, impedance spectroscopy method for measurement of the equivalent serial resistance and analysis of the dynamic parameters. The measured and calculated parameters are: equivalent serial resistance (ESR), ...
