  • CAN transmitter with fast CANL loop and switched output cascode
    Patent number: 11936496
    Abstract: A controller area network (CAN) transmitter includes an output stage circuit including a CANH port and a CANL port, and an input stage circuit configured to receive an input signal. The input signal is configured to indicate whether the output stage circuit is to provide dominant or recessive states. The CAN transmitter includes a cascode circuit configured to provide output signals on the output stage circuit to provide dominant or recessive states based on the input signal. The CAN transmitter includes a switch circuit configured to, based upon the input signal, switch the cascode circuit on and off.

  • Method and apparatus for driving a direct current or voltage controlled oscillator with modulation slope feedback
    Patent number: 7129788
    Abstract: A d.c. signal controlled oscillator includes a frequency-determining network having a control input and a modulation input. A phase regulating loop includes the oscillator and components that provide a control signal to the control input. A circuit apparatus for driving the oscillator includes a modulation generator that provides a modulation signal to the modulation input, and a circuit arrangement that autonomously generates a signal depending on and representing a slope of the modulation and provides this slope signal to the modulation generator, which generates the modulation signal dependent on the slope signal.
