Hamid Sadat Mansoury, Saeed Saeedi, M. Atarodi · 2024
A FlexRay receiver that is capable of operating within [−60V, 60V] common mode range using a common mode cancellation method is presented in this paper. The receiver uses 5V M OSFE T transistors and incorporates a digital block to reduce the required number of comparators to 2, potentially leading to lower power consumption and die area. Extensive simulations have been conducted to ensure the receiver's functionality within a temperature range of$[-40^{\circ}\mathrm{C},\ 150^{\circ}\mathrm{C}]$, which is particularly crucial for automotive applications. Furthermore, corner and mismatch simulations have been performed to ensure the circuit's process tolerance and suitability for mass production. Additionally, Electromagnetic Immunity simulations have been performed to ensure that the receiver, intended for automotive applications, meets the necessary standards. The layout of the receiver occupies an area of$153.6 \times 128.7\mu \mathrm{m}^{2}$.
