Abstract :
A Transition Controllable Noise Source (TCNS) generates substrate noises with controlled transitions in size, interstage delay, and direction. The noises are measured in a 100 ps 100 μV resolution by a linear substrate voltage detector that uses a front-end PMOS source follower probing substrate potential and a back-end latch comparator for sampling/digitizing the source follower output. A 0.4 μm CMOS test chip demonstrates the effectiveness of these circuits in performing advanced research on substrate noise
