    Abstract: A method for providing an improved active pixel sensor cell having a soft-saturation circuit. The method includes providing a pixel node and a photodiode coupled to the pixel node. The photodiode receives light and converts the light into an electrical signal representative of light. A soft-saturation circuit for selectively affecting the electrical signal at the pixel node based on the electrical signal at the pixel node based on the electrical signal at the pixel node is also provided.

    Abstract: A circuit that includes at least two driver circuits. Each driver circuit receives analog information and drives a value related to the analog information to an analog bus. Each driver circuit also includes a select transistor to pass the value related to the analog information to the analog bus when the driver circuit is selected. The select transistor includes a source and a bulk. Each driver circuit further includes a bulk potential control circuit (BPCC) to couple the bulk to the source when the driver circuit is selected and to couple the bulk to a voltage supply when the driver circuit is not selected.

    Abstract: A transition detector circuit produces an output pulse upon detection of a transition at any one of several input nodes using a single delay path so all input transitions produce the same output pulse width and with only one gate delay in the circuit. The circuit includes precharging means, coupled between the plurality of transitioning inputs and the output node, for charging the output node high. The precharging means comprises stacked field effect transistor (FET) devices, each having a gate connected to a respective one of the transitioning inputs. A first charging device for charging the output node high is coupled to the output node. A second charging device for discharging the output node low is coupled to the output node. A single delay means, coupled between the plurality of transitioning inputs and both the first and second charging devices, both turns off the first charging device and turns on the second charging device. Switching means, controlled by the plurality of transitioning inputs and coupled between the output node and the second charging device, disconnects the second charging device from the output node.
