Abstract :
New compact switched current memory cells (CMCs) are proposed, which still maintain the properties of insensitivity to transistor mismatch, channel-length modulation and current sharing. Both class A and class AB structures are investigated, of which the former type has about the same or somewhat better performance than the ordinary memory cell, and the latter type outperforms both of them with respect to power consumption and clock feedthrough. The performance of the proposed structures when used in integrators is also shown.
