Abstract: This paper presents the output voltage estimation of bipolar junction transistor (BJT) common emitter (CE) using iterated extended Kalman filter (IEKF). For this, state space model has been derived using Kirchhoff’s current law (KCL) and Ebers-Moll model of the transistor. The performance of IEKF has been compared with extended Kalman filter (EKF). The simulation results show large signal to noise ratio (SNR) and small root mean square error (RMSE) using IEKF as compared to EKF, as IEKF considers the error due to linearization. The advantage of the proposed method is that the derived extended state space equation can be used for parameter estimation of both, the transistor state and transistor parameters as the derivation includes transistor model.
