Measurement of Resistance Standards by a Precision LCR Meter at Frequencies up to 2 MHz
Jürgen Schurr, Shakil A. Awan
We report on two-terminal-pair and four-terminal-pair test measurements of a 10-kohm resistance standard by means of a commercial precision LCR meter at frequencies up to 2 MHz. In…

Resistance standards with calculable, nearly negligible AC-DC difference at frequencies up to 2 MHz for the calibration of precision LCR meters
Jürgen Schurr, Rolf H. Judaschke, Shakil A. Awan
We have developed novel impedance standards based on thin-film surface-mount-device (SMD) resistors. Due to the small dimensions of such resistors, the quantities determining their…

Sensitivity Comparison of Macro- and Micro-electrochemical Biosensors for Human Chorionic Gonadotropin Biomarker Detection
Samar Damiati, Carrie Haslam, Sindre Søpstad +4
Selectivity and sensitivity are important figures of merit in the design and optimization of electrochemical biosensors. The efficiency of the fabricated immunosensing surface can…
