We study how to generate binary de Bruijn sequences efficiently from the class of simple linear feedback shift registers with characteristic polynomial f(x)=x^n+x^n-1+x+1 ∈F_2[x], for n ≥ 3, using the cycle joining method. Based on the properties of this class of LFSRs, we propose two classes of successor rules, each of which generates O(2^n-3) de Bruijn sequences. The cost to produce the next bit is O(n) time and O(n) space for a fixed n.
