Definitions

  • the present invention makes use of the fact that certain forms of electronic valves under me suitable conditions of operating potentials will inherently exhibit negative resistance effects.
  • Such valves are herein referred to as negative resistance Valves.
  • the anode currentanode voltage characteristic of the well-known screened grid valve is a curve having a sharply rising portion followed by a. portion which is substantially linear and which slopes downwardly, this falling portion being again followed by a rising portion. It will be apparent that between y the two rising portions of the characteristic i. e.
  • the anode circuit of the valve I includes the usual output device which is connected at the terminals 1, anode potential being applied to the valve I from a battery 8. Regeneration is obtained by means of a negative resistance screened grid valve 9 whose plate is connected to the grid end of the tuned input circuit 5, 6, and whose cathode is connected to a movable tapping point I0 upon a potentiometer resistance II.
  • Control grid bias for the valve 9 is obtained by means of an adjustable potentiometer I2 in association with a battery I3 as shown, the total bias upon this control grid including also any potential which may occur across that part of the resistance II which is included between grid and cathode of the said valve 9. Screen grid potential is applied to the Valve 9 from the battery 8 as shown.
