In this paper the intrinsic transconductance, output current, output power and their nonlinear derivatives are analyzed for double and single channel HEMTs. It is shown that the distortion products weakly depend on device's gate width dimension. Conversely, it is strongly affected by the 2DEG sheets in the quantum wells. The more the number of device's active channels, the higher the current and subsequently...
There are many systems in our daily lives that utilise feedback controllers. However, the importance of these controllers is often overlooked as they are hidden or embedded within the systems that they aim to control. Examples and applications include the numerous feedback loops employed in electrical, mechanical and chemical systems and also those present in nature, such as the circadian cycle. Considering...
