TRENDS IN ELECTRONICS ENGINEERING

  • The basic principle of operation of thermionic diodes was discovered by Frederick Guthrie in 1873
  • In 1904, the vacuum-tube diode was introduced by J. A. Fleming.
  • In 1906, Lee De Forest added a third element, called the control grid, to the vacuum diode, resulting in the first amplifier, the triode.
  • In1930s the four-element tetrode and five-element pentode gained
  • prominence in the electron-tube industry.
  • 5. On December 23, 1947, Walter H. Brattain and John Bardeen
  • demonstrated the amplifying action of the first transistor at the Bell
  • Telephone Laboratories.

6. Drs. Ian Munro Ross (front) and G. C. Dacey jointly developed an

experimental procedure for measuring the characteristics of a field-effect

transistor in 1955.

7. An op-amp is first found in US Patent 2,401,779 "Summing Amplifier" filed by Karl D. Swartzel Jr. of Bell labs in 1941.

8. The popularity of monolithic op-amps was further improved upon the release of the LM101 in 1967, which solved a variety of issues, and the subsequent release of the μA741 in 1968.
