The operation point of the transistor is called biasing. Biasing is done before performing the small-signal analysis. To bias, the transistor, positive gate voltage is applied to the transistor. In this given circuit, VS is the small signal where the …
MOS refers to Metal-Oxide-Semiconductor, and MOSFET refers to Metal-Oxide-Semiconductor Field Effect Transistor. MOSFET has four terminals: drain, source, bulk, and gate. There are two types of MOSFET: NMOS type transistor and PMOS type transistor. The below figure shows the cross-section …
We know that the unit of power is watts; however, in RF systems, we measure power in decibels. A decibel is a logarithmic unit that indicates ratio or gain. When converting the power to decibels, it is compared to a …
Maximum power delivery is the main objective while designing a circuit in RF systems and the purpose of creating matching networks is to maximise the power transfer with very minimum loss.The diagram shows the antenna and Low Noise Amplifier (LNA) …
Maximum power is an important feature in RF systems. The main objective while designing a RF circuit is to have maximum power transfer with minimum loss to avoid wasted power. For example, while designing an antenna the aim is to …
The combination of real and imaginary values makes up a complex number. It is represented in the form of “R+jX,” where R is the real part and jX is the imaginary part. In a two-dimensional cartesian plane, the real components …
The RF circuits and blocks are analyzed in terms of power quantity; hence, in RF systems, we are more concerned about the power quantity rather than the voltage and current, for example, the power gain, which is the ratio of …
Power in circuits Power by definition is the product of current and voltage in a circuit. Power is an essential aspect to be considered while designing radio frequency and microwave circuits. The main aim while designing a circuit is to …
