Modelisation and simulation of integrated super-regenerative receivers

2002

Abstract

This paper is dedicated to an in-depth analysis of super-regenerative receivers performances. A preliminary study of negative conductance variation according to the oscillator amplitude is first achieved. Then a computer method is proposed to simulate a super-regenerative receiver with and without Automatic Gain Control. The variation of the gain and adjacent signal rejection with the increase of the RF input power signal is explained.

Superheterodyne receiver

A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. It was long believed to have been invented by US engineer Edwin Armstrong, but after some controversy the earliest patent for the invention is now credited to French radio engineer and radio manufacturer Lucien Lévy. Virtually all modern radio receivers use the superheterodyne principle.

Antique radio

An antique radio is a radio receiving set that is collectible because of its age and rarity. The first radio receivers used a coherer and sounding board, and were only able to receive CW continuous wave (CW) transmissions, encoded with Morse code (wireless telegraphy). Later wireless telephony|transmission and reception of speech became possible, although Morse code transmission continued in use until the 1990s. All the following sections concern speech-capable radio, or wireless telephony.

Gain (electronics)

In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal. It is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. It is often expressed using the logarithmic decibel (dB) units ("dB gain").
