US Patent 7755424 - Mem-resistor crossbar FPAAs

http://www.freepatentsonline.com/7755424.html

This is one of my patents related to a mem-resistor crossbar design used to implement field programmable analog arrays. More information on my patents is available at this link. Claim 1 reads:

1. A control circuit including:

an operational amplifier having an inverting input, a non-inverting input, and an output;

an array of impedance elements connected to the output of the operational amplifier, wherein the array of impedance elements includes capacitors; and

a resistance switch crossbar array configured to store data in the form of high or low resistance states, wherein the resistance switch crossbar array is electrically connected between the array of impedance elements and the inverting input of the operational amplifier.
