Diode Circuits Tutorial (PDF 25p): Initially both semiconductors are totally neutral. The concentration of positive and negative carriers are quite different on opposite sides of the junction and the thermal energy-powered
diffusion of positive carriers into the N-type material and negative carriers into the P-type material
occurs. The N-type material acquires an excess of positive charge near the junction and the P-type material acquires an excess of negative charge.

A SINGLE DIODE CIRCUIT: This page describes a single diode circuit. Most of the power electronic applications operate at a relative high voltage and in such cases, the voltage drop across the power diode tends to be small. It is quite often justifiable to use the ideal diode model. An ideal diode has zero conduction drop when it is forward-biased and has zero current when it is reverse-biased. The explanation and the analysis presented below is based on the ideal diode model.

A DIODE CIRCUIT WITH A FREE-WHEELING DIODE: The circuit shown above differs from the circuit described in the previous page, which had only one diode, labelled D1. This circuit has another diode, marked D2 in the circuit shown above. This diode is called the free-wheeling diode. The circuit operation is described next. The explanation is based on the assumption that the reader knows how the circuit without a free-wheeling diode operates.

LM311 Voltage Comparator (PDF): The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710. They are also designed to
operate over a wider range of supply voltages: from standard �15V op amp supplies down to the single 5V supply used for IC logic.

Electromagnetic Communication Lecture Notes: The decoding of DSB-AM signals involves the least complexity, but the redundancy of the information carried by the two sidebands implies an inherent inefficiency in terms of both radiated power and frequency space
utilization.
