  • Power stealing circuit to charge a capacitor
    Publication number: 20020186070
    Abstract: A power stealing circuit to charge a capacitor includes a passive electrical power channel. The passive electrical power channel has an input connected to an input signal and an output designed to be connected to the capacitor. An active electrical power channel is powered by the capacitor. The active electrical power channel has an input connected to the input signal and an output connected to the capacitor.

  • Preamplifier circuit for a photodetector
    Publication number: 20020105385
    Abstract: An amplifier circuit (20) for a photodetector includes a transconductance variable gain stage (32). The transconductance variable gain stage (32) has an input (34) capable of connecting to the photodetector and an output (40). A transconductance gain stage (44) has an input (42) connected to the output (40) of the transconductance variable gain stage (32). A feedback resistor (46) is connected between an output (48) of the transconductance gain stage (44) and the input (42) of the transconductance gain stage (44).
