Abstract: An apparatus and method and system therefor relates generally to decision threshold control. In such an apparatus, an ac-coupler circuit is configured as a high-pass circuit path for a first frequency range. A buffer amplifier circuit is coupled in parallel with the ac-coupler circuit. The buffer amplifier circuit is configured as a low-pass circuit path for a second frequency range. An offset injection circuit is coupled to both the ac-coupler circuit and the buffer amplifier circuit and configured to inject an offset.
