  • Termination circuits and methods therefor
    Patent number: 6008665
    Abstract: An active termination circuit for terminating a transmission line in an electronic device. The active termination circuit is configured to clamp a voltage level on the transmission line to one of a first reference voltage level and a second reference voltage level. The active termination circuit includes a first clamping transistor coupled to a transmission line terminal and a first terminal. The transmission line terminal is configured to be coupled to the transmission line in the electronic device. The first terminal is configured to be coupled to the first reference voltage level in the electronic device. There is included a second clamping transistor coupled to the transmission line terminal and a second terminal. The second terminal is configured to be coupled to the second reference voltage level in the electronic device. There is also included a first threshold reference device coupled to the first clamping transistor.
