Conventional discrete time mode reconfigurable analog circuits are designed with the switched capacitor technology

which have the disadvantage of function limitation

lower band pass

and being not compatible with digital CMOS process technology in hybrid integrated circuits.This paper presented a Reconfigurable Analog Circuit (RAC) based on Current Mode Sampled Data Technology (CMSDT)

which was fully compatible with the digital CMOS process.The Configurable Analog Block (CAB) based on switched current technology was developed

and the programmable interconnect network structure for the switched current CAB was proposed.Three analog circuits for application examples have been achieved respectively by reconfiguration in the 4×2 reconfigurable analog array.The simulation experimental results show that the designed reconfigurable analog circuit is effective and can realize multi-function analog circuit with reconfiguration.
