PROJECT TITLE :

Figures-of-Merit to Evaluate the Significance of Switching Noise in Analog Circuits

ABSTRACT:

An analysis flow is proposed to determine the importance of induced (switching) noise in analog circuits. The proposed flow is exemplified through 2 commonly used amplifier topologies. Specifically, input-referred switching noise is introduced as the primary figure-of-advantage and compared with the well-known equivalent input device noise through analytic expressions. The comparison is achieved as a function of multiple parameters that characterize switching noise within the time domain (modeled as a decaying sine wave), like peak amplitude, period, oscillation frequency inside each amount, and damping coefficient. The analytic expressions used to get input-referred switching and device noise are verified with SPICE simulations. These expressions are utilised to develop dominance regions for both noise sources. Furthermore, time-domain switching noise amplitude (at the majority node) at that the input device and switching noise magnitude are equal (in the frequency domain) is determined as the second figure-of-advantage, providing guidelines for the signal isolation method. Reverse body biasing is additionally proposed to alleviate the result of switching noise by weakening the bulk-to-input transfer function versus reducing the switching noise amplitude at the majority nodes. It is demonstrated that this technique incorporates a negligible result on primary style objectives of the victim circuit whereas reducing the input-referred switching noise by up to ten dB. As a case study, the proposed flow is applied to a potentiostat circuitry where input sensitivity is of primary importance.
