Patent GB-2175766-A (GB)
Title: Fibre optic communication systems
Inventor: RAVEN ANTHONY LOVELL
IPC: H01S3/067
Filed: 1986-05-22
Abstract: Repeater amplifier in which a diode laser (20) or LED is coupled to a fibre link to activate the latter and provide positive gain, the link comprising a length (12) of the fibre optic transmission line doped with Neodymium or Erbium. An improved transmission line is described in which the line is effectively formed as a continuous repeater amplifier by doping the fibre optic line with Neodymium or Erbium to an amount just sufficient to cancel out line losses for optical signals transmitted therealong. Typical operaing wavelengths for the diode laser are 700 - 900nm. An advantage has been found by employing a carrier for the light signals of 1.318 microns for Neodymium doping and 1.54 microns for Erbium doping.

Title: High voltage FET circuit
Inventor: GUILLOT PIERRE
IPC: H03K17/0814
Filed: 1987-02-07
Abstract: A circuit using complementary FETS for use with a supply voltage which is higher than the breakdown voltage of the individual transistors of the circuit uses pairs of transistors (1, 5) to connect circuit nodes, one transistor (3) of each pair having a bias voltage applied to its control electrode such that the voltage appearing across the individual transistors is less than their breakdown voltage. The bias voltage is controlled by a supply voltage sensing circuit (12) which controls the bias voltage according to the level of supply voltage in use. The circuit can be used in an EPROM where a high supply voltage (20v) is used when the memory is being programmed, and a low supply voltage (5v) is used at other times. The control circuit ensures that damage does not occur when the supply voltage is in transition between its high and low conditions. <IMAGE>
