I am learning renormalization by myself. I aim to understand one-loop calculations in $\phi^4$ theory in d dimensions and one-loop calculations in Quantum Electrodynamics. I have looked at Peskin and Schroeder but find it tough to follow. Are there any better books or lecture notes to accomplish this?
