Abstract :
In this paper, a multiple function filter with configurable capability for 1-V supply voltage is proposed. The circuit can find a rank order among a set of input voltages by setting different binary signals. Moreover without modifying the circuit, the WTA/k-WTA, maximum, minimum and medium function can be easily configured. The circuit has been designed using 0.5 μm 2P2M CMOS technology. Seven input voltages are used to verify the performance of the circuit. The results of HSPICE simulation show that the operating speed of the circuit is 2 μs for each rank-order operation, that the input dynamic range is rail-to-rail, and that the resolution is 10 mV for 1 V supply voltage. The static power dissipation of the circuit is 11 μW
