Reducing AC impedance measurement errors caused by the DC voltage dependence of broadband high-voltage bias-tees [PDF]

open access: yes, 2007
During the AC impedance characterization of devices, from the kHz-range up to the GHz-range, accuracy can be lost when a DC voltage is applied. Commercial high-voltage broadband bias-tees are often voltage-dependent, which can cause inaccuracies at low ...

Doping-Less SiC p-i-n Diode: Design and Investigation

open access: yesIEEE Access, 2021
We introduce a novel high-voltage SiC p-i-n diode considering a charge plasma approach. This technique facilitates the formation of the anode and the cathode regions within the silicon carbide without requiring any impurity doping by taking advantage of ...

PIN diode driver for NMR and MRI [PDF]

open access: yesJournal of Magnetic Resonance, 2019
Designing custom coils for magnetic resonance systems, such as nuclear magnetic resonance (NMR) spectrometers and magnetic resonance imaging (MRI) scanners, often entails using non-standard configurations of the transmit-receive (T/R) switch and Q-spoiling circuits.
