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...

this paper presents a design of an uwb downconversion integrated cmos resistive ring mixer with linear voltage regulator (lvr), to supply required biasing voltages for the mixer section. the designed mixer circuit has been optimized for using in heart rate extraction system with microwave doppler radar at 2.4ghz frequency. this mixer needs 2 dc bias voltages equal to 0.5 and 1 volts for its bes...

A latchup current self-stop methodology and circuit design, which are used to prevent damage in the bulk CMOS integrated circuits due to latchup, are proposed in this paper. In a bulk CMOS chip, the core circuit blocks are always latchup sensitive due to a low holding voltage of the parasitic SCR path. The proposed latchup prevention methodology and circuit design can detect and stop the occurr...

Fabrication of an integrated circuit with smaller area, besides reducing the cost of manufacturing, usually causes a reduction in the power dissipation and propagation delay. Using the static CMOS technology to fabricate a circuit that realizes a specific logic function and occupies a minimum space, it must be implemented with continuous diffusion runs. Therefore, at the design stage, an Euleri...
