Abstract :
An analogue signal generated from a periodically reproduced bitstream pattern from a SigmaDelta modulator output can be used in the testing of mixed-signal devices. This paper discusses an ASIC design which examines the implementation issues and design considerations of single and multi-bit quantizers in memory based analogue signal generation. Special emphasis is placed on multi-bit signal generation in which two methods are explored to overcome the linearity issues associated with multi-bit DACs, without the requirement of additional silicon area.
