hi Asmodeus, i guess it depends on the where you want to use that bias.most Popular biasing scheme is high swing cascode, which is available in text books. You can extend the same architecture for different cascode levels, but with my experience i learnt that REPLICA biasing is the best one.Coming to your beta multiplier people are using error amplifier to bias top current mirror load with out using diode connection.Hope this helps.
Thanks, Rajasekhar.
