An Inspection Based Method to Analyse Deterministic Noise in N-port Circuits

This paper proposes the estimation by inspection method to analyse the impact of deterministic supply noise on the design specifications of the analog and mixed signal (AMS) systems. The method is based on the indefinite admittance matrix (IAM) method. The voltage gain, phase and input-output impedance have been considered as the design specifications. To validate the method, two examples of output stages for analog and digital blocks have been simulated in standard 0.18 $\mu$m technology with 1.8 V of supply and same geometric area. The proposed models using the inspection method and the SPICE based simulations shows maximum mean percentage error (MPE) of 3% for all the examples.
