  • Patent number: 5541564
    Abstract: A hybrid R-C component for use in oscilloscope probes of the type having a resistive element disposed on a first surface of a substrate, and having a first conductive coating disposed on a second surface of the substrate, and having a dielectric layer disposed over the first conductive coating, a second conductive coating partially disposed over a first portion of the substrate and in contact with a first end of the resistive element and with a region of the second conductive coating being partially disposed over the dielectric layer and forming a first capacitor plate, a third conductive coating disposed over a second portion of the substrate and in contact with a second end of the resistive element and with a region of the third conductive coating being partially disposed over the dielectric layer and forming a second capacitor plate, whereby the first capacitor plate and a first area of the first conductive coating in conjunction with the dielectric layer form a first capacitor C1 and the second capacitor

  • Patent number: 4642744
    Abstract: A regulated high voltage supply derives two regulated high voltages from a single winding of a transformer. The higher voltage supply is primary side pass regulated, and the lower voltage supply is secondary side offset regulated. The two regulating circuits for the two regulated high voltage supplies interact with each other to correct an error in either high voltage supply.

  • Patent number: 4146846
    Abstract: An amplifier includes a network which generates additional output current for driving a substantially capacitive load as the frequency of an input signal is increased. The network comprises a plurality of rate discriminators which activate additional current sources at predetermined frequencies.
