LNA Design Iulian Rosu‚ YO3DAC / VA3IUL http://www.qsl.net/va3iul/ An LNA combines a low noise figure‚ reasonable gain‚ and stability without oscillation over entire useful frequency range. The Low Noise Amplifier (LNA) always operates in Class A‚ typically at 15-20% of its maximum useful current. Class A is characterized by a bias point more or less at the center of maximum current and voltage capability of the device used‚ and by RF current and voltages that are sufficiently small relative

2.8 GHz Narrow-Band Colpitts Voltage Controlled Oscillator Design Literature Survey Report Bilkent University Electrical&Electronics Engineering Abstract Oscillators are one of the main building blocks of the electronic devices. They work on the principle of oscillation which is a periodic fluctuation between the maximum and minimum value of the quantity. Oscillators mainly consist of two parts: the active circuit and the resonator. In active circuit there are active circuit elements

transmission of electrical energy from a power source to an electrical load without man-made conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. So a study was made on the investigation of wireless power transmission by near-field coupling from the view point of the antennas. Mainly the antennas are of two types - dipole and loop antennas – and were used as the transmitting antenna and the receiving antenna for electrical near-field

FEEDBACK AMPLIFIER FEED BACK: The process of applying a fraction of output energy of some device back to the input is known as feedback. FEEDBACK AMPLIFIER: The amplifier using feed back process is called feedback amplifier. TYPES OF FEEDBACK AMPLIFIER: There are two types of feedback amplifier: a)Positive feedback amplifier b)Negative feedback amplifier POSITIVE FEEDBACK AMPLIFIER: >The amplifier in which feedback energy is applied in the same polarity or in same phase is called

steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The ohm (R)‚ a unit of electrical resistance‚ is equal to that of a conductor in which a current (I) of one amp is produced by a potential of one volt (V) across its terminals. These fundamental relationships represent the true beginning of electrical circuit analysis. Current flows in an electric circuit in accordance with several definite laws. The basic

Ammeter An ammeter is used to measure current. Voltmeter A voltmeter is used to measure voltage. Resistor (Fixed and Variable) Fixed Variable A resistor restricts the flow of current‚ for example to limit the current passing through an LED. A resistor is used with a capacitor in
