Latest Patents

Malcolm Spencer holds a patent for an optical fibre receiver. This invention is designed for use with optical fibre or for receiving a beam in free space. The optical receiver features a detector device, typically a PIN diode, connected in series with a resistor and to the base of a gallium arsenide field effect transistor (FET). While the FET performs well at most frequencies, instability can arise at Gigahertz frequencies under certain load conditions. To address this issue, Spencer's design incorporates a 50-ohm resistor in series with a capacitor, which helps to suppress instability. Additionally, the FET is coupled to a bipolar transistor amplifier through a long wire bond that acts as an inductive impedance at critical frequencies.
