Physics Based Analytical Model for Charge Storage in an Ideal Heterostructure Barrier Varactor
Mirosław Adamski , Janusz A. Dobrowolski
AbstractAn ideal Heterostructure Barrier Varactor (HBV) is defined as a device with no leakage current. Space charge storage in the cladding regions with uniformly doped modulation layers and undoped spacers is analyzed using the Thomas-Fermi equilibrium model and Joyce-Dixon approximation. The resulting Q-V characteristics of the cladding regions are given in closed-form parametric expressions, with the electron concentration as the independent variable. C-V characteristics of the HBV is also given parametrically with charge as the device state variable. The calculated C-V characteristics are in excellent agreement with the measured data
