In this paper a new method is proposed for observing analog test points inside integrated circuits that enables the simultaneous observation of a large number of points. The method permits the removal of the analog multiplexer from the signal path and a reduction of the load introduced at the observed test points. A charge coupled device analog shift register is used to sample input voltage and shift out a charge that is proportional to the input voltage.
