Abstract: A configurable impeder is provided. The configurable impeder comprises of multiple CESs. Each of the CESs is capable of being configured into one of a plurality of impedance states. Further, a programing circuit is provided. The programing circuit provides a plurality of programing signals in dependence of an input signal. Each programing signal configures an impedance state of a respective CES from the plurality of CESs.

Abstract: A Circuit architecture and a method for rapid and accurate statistical characterization of the variations in the electrical characteristics of CMOS process structures, MOS devices and Circuit parameters is provided. The proposed circuit architecture and method enables a statistical characterization throughput of <1 ms/DC sweep at <2 mV or <1 nA resolution accuracy of variations in voltage or current of the device under test. Salient features of proposed circuit architecture include a programmable ramp voltage generator that stimulates the device under test, a dual input 9-11 bit cyclic ADC that captures input and output DC voltage/current signals to/from the device under test, a 2 Kb latch bank that captures 9-11 bit streams for each measurement point in a DC sweep of programmable granularity and a clocking and control scheme that enables continuous measurement and stream out of digital data blocks from which the analog characteristics of the devices under test are reconstructed post measurement.
