A design-for-test (DFT) technique for analogue circuits is proposed which splits all high current transistors into two. This technique reduces the fault-masking effects of the fault-free parts of the circuit, giving a potential fault cover of over 99%. Other advantages are the small area overhead and a low performance penalty
