When chopping is applied to a continuous-time sigmadelta modulator (CTΣΔM), quantization noise fold-back often occurs, leading to increased in-band noise. This can be prevented by employing a return-to-zero (RZ) digital-to-analog converter (RZ DAC) in the modulator's feedback path and arranging the chopping transitions to coincide with its RZ...

This paper describes the design of a precision bipolar junction transistor based temperature sensor implemented in standard 0.7-μmCMOS technology. It employs substrate p-n-ps as sensing elements,which makes it insensitive<br/>to the effects of mechanical (packaging) stress and facilitates the use of low-cost packaging technologies. The sensor...
