Abstract
An impedance analyzer is provided. The analyzer includes a signal excitation generator comprising a digital to analog converter, where a transfer function of the digital to analog converter from digital to analog is programmable. The impedance analyzer further includes a receiver comprising a low noise amplifier (LNA) and an analog to digital converter (ADC), where the LNA is a current to voltage converter; where the programmable digital to analog transfer function is implemented by a direct digital synthesizer (DDS) and a voltage mode digital to analog converter, or a digital phase locked loop (PLL), or both. Further, a multivariable sensor node having an impedance analyzer is provided. Furthermore, a multivariable sensor network having a plurality of multivariable sensor nodes is provided.
