Abstract
An integrated circuit including at least one circuit node, multiple duplicate circuit blocks integrated on the integrated circuit in close proximity with each other, each including at least one device that is susceptible to random telegraph noise (RTN), and a switch circuit that swaps electrical coupling of the duplicate circuit blocks, one at a time, to the at least one circuit node in sequential cycles of a clock signal. The duplicate circuit blocks may be large functional blocks, such as an oscillator or a comparator or the like, or limited to circuits including RTN susceptible devices, such as differential pairs or the like. Each duplicate circuit block may include any number of connections for coupling to corresponding circuit nodes. The swapping may further include chopping in which multiple inputs are swapped with each other while multiple outputs are swapped with each other in consecutive clock cycles.
