Abstract

The present disclosure provides for transimpedance amplifiers for crossbar circuits. A crossbar circuit may include a plurality of bit lines intersecting with a plurality of word lines and a plurality of cross-point devices. Each of the plurality of the cross-point devices is connected to at least one of the word lines and at least one of the bit lines. The crossbar circuit may further include a transimpedance amplifier to generate an output voltage representative of a sum of currents flowing through a first bit line of the plurality of bit line. The transimpedance amplifier may include an operational amplifier, a current mirror circuit connected to an output of the operational amplifier, and one or more resistors connected to the current mirror circuit and a supply voltage.
