a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

introduction: high frequency alternating currents is a safe, reversible and selective method for nerve conduction block that has been under study during the last decade as a treatment for the diseases involving abnormal neural impulses. however, reducing the stimulus amplitude, and the undesired onset response, as well as optimizing the stimulus parameters for more effective block is still unde...
