    Inventor: David Bingham
  • Circuit means for converting a bipolar input to a unipolar output
    Patent number: 4473757
    Abstract: A circuit which accepts an input signal of either positive or negative polarity and produces an output signal having an open circuit voltage similar in amplitude to the input signal amplitude but having a defined polarity. A plurality of switching elements, preferably MOS transistors, are connected in a bridge circuit, the bridge circuit having a pair of input terminals responsive to the input signal and a pair of output terminals for providing the output signal, the switching elements being connected between the input and output terminals. Each of the switching elements has a control input connected to one of the input terminals whereby each of the switching elements automatically opens or closes in response to the polarity of the input signal to maintain the defined polarity of the output signal.

  • Commutating signal level translator
    Patent number: 4195266
    Abstract: A system or circuit for signal level translation by information storage on multiple capacitors subjected to commutation at a frequency higher than the highest preserved frequency component of the signal. Continuous level translation of information, such as successive voltage levels, is accomplished with very small error. The invention is particularly applicable to instrumentation amplifiers for example, wherein differential input voltages are required to be referenced to some other base voltage such as zero or ground voltage.

  • Commutating autozero amplifier
    Patent number: 4190805
    Abstract: An active analog signal processing system preferably embodied as an integrated circuit includes a pair of like amplifiers which are alternately switched between a first signal processing mode and a second zeroing mode in which a capacitor in the amplifier circuit is reverse charged to a voltage level equivalent to the average noise voltage level of the system whereby the system automatically cancels the low frequency noise thereof to provide a simple low noise processing system.
