In this paper, we propose a multistage transimpedance amplifier (TIA) based on the local negative feedback technique. Compared with conventional global-feedback technique, proposed TIA has advantages of wider bandwidth, and lower power dissipation. The schematic characteristics circuit are described. Moreover, employs inductive peaking to increase bandwidth. is implemented using 65 nm complemen...

A new implementation of Chua’s chaotic circuit using current feedback operational amplifier (CFOAs) and giving high frequency oscillations is presented. Both the circuit topologies based on CFOA’S i.e. CFOA based nonlinear resistor and CFOA based synthetic inductor are used together The new circuit is operated at high frequencies in which the CFOAs have excellent performance. The workability of...

Salmonella enterica serovar Typhimurium is a common food-borne pathogen that induces inflammatory diarrhea and invades intestinal epithelial cells using a type three secretion system (T3SS) encoded within Salmonella pathogenicity island 1 (SPI1). The genes encoding the SPI1 T3SS are tightly regulated by a network of interacting transcriptional regulators involving three coupled positive feedbac...

Circuit topologies are introduced which should prove of use to the circuit designer of analog audio amplifiers. The objective is to produce circuits of' modest complexity that overcome the nonlinearities inherent in single-transistor and long-tail pair circuits. This allows amplifiers with excellent linearity to be designed without resorting to overall negative feedback with high loop gains. To...

With one operational amplifier (op-amp) in negative feedback, the traditional zero potential circuit could access one element in the two-dimensional (2-D) resistive sensor array with the shared row-column fashion but it suffered from the crosstalk problem for the non-scanned elements' bypass currents, which were injected into array's non-scanned electrodes from zero potential. Firstly, for supp...
