Definitions

  • the reset circuit 230 may include a switch SWi for coupling the output 220 of the integrator 210 to the input of the integrator 210 in order to discharge the integrator 210.
  • the closing of the switch SWi may be controlled by the reset pulse as described in the examples above.
  • the switch SWi may be provided by one or more transistors.
  • the switch SWi may be provided by one or more field effect transistors “FETs” such as a MOSFET or a JFET, or by one or more bipolar transistors.
  • the reset circuit 230 may include a current source.
