This thesis presents noise analysis of translinear circuits, or in general, log-domain filters. Due to the inherit companding [sic] behaviour and nonstationary nature of the translinear noise sources, a nonlinear noise analysis method is proposed. Based on the large-signal calculation, the first-order noise and signal-noise intermodulation terms are considered. Overall, two important noise specifications, power spectral density and signal-to-noise ratio, of both static and dyamic translinear circuits are computed. For dynamic translinear circuits, two methods, either combining noise sources and moving them to output, or process them in situ and individually, are elaborated. A number of generic examples are illustrated to demonstrate the effectiveness and applications of the methods.
