A current switching circuit has greatly reduced charge injection effects with the introduction of a mirror path to mirror the switch path. The mirror path comprises a complementary switch and a pulling amplifier, e.g., a pull-down amplifier for a source current switching circuit, or a pull-up amplifier for a sink current switch circuit. The pulling amplifier mirrors the status of an output path of a current source, e.g., a transistor current source, such that when the current source is switched ...

An apparatus and method for converting an analog signal to a digital signal. The apparatus includes a plurality of capacitors. The plurality of capacitors includes at least a first capacitor, a second capacitor and a third capacitor.

An asynchronous wait state generator circuit and method is included in a dual port device, e.g., in a dual port memory, to allow the use of separate address decoders and simultaneous access to memory locations from asynchronously operating, separate ports. When an address collision is detected between accesses on both ports of a dual port device, a wait state signal is generated for the relevant port having the later attempt to access the same memory or other addressable location. In the unique ...
