Here you will find some new ideas (and their implementations) about semiconductor devices which, we believe, are worth to read through. In doing so you become aware of their principles of operation, their (rather simple) technology and possible applications. In particular, you will be informed how to produce a variable capacitor (varicap or varactor) and transistor with linear dependence of capacitance or current versus applied voltage. More importantly, you will be introduced to voltage-contr
The present site is established in order to provide a worldwide access to some basic principles of construction and functioning of a new classes of semiconductor devices including:
variable capacitances (varicaps or varactors) with unprecedently wide tuning range (C max / C min = 10 2 - 10 4 ) and, simultaneously, with almost any prescribed capacitance-voltage dependence (in particular - linear );
