This paper describes a CMOS rail-to-rail class AB operational amplifier designed to have extremely low output impedance and large current-drive capability. The amplifier uses an innovative output stage, having both source follower and common source stages working simultaneously throughout the output common-mode range. The source follower ensures low output impedance, which enables it to drive r...

This paper introduces four new resistorless circuits of first-order current-mode all-pass filter (CMAPF) based on dual-X current conveyor transconductance amplifier (DXCCTA). All the four circuits use a single DXCCTA and a capacitor for their realization. The main features of the proposed CMAPFs are: use of minimum active and passive components, resistorless realization, electronically adjustab...

This paper presents a ultra wideband low noise amplifier for 6GHz Applications. This proposed LNA is the extension of inductively common source amplifier and in this design we used transistor multifingering techniques in order to reduce noise and improves gain. This LNA is simulated by using UMC .18um CMOS mixed signal/RF process in cadence virtuoso. In this design, used current source biasing,...

A new emulator circuit for designing memcapacitor is proposed in this work. The suggested designed using a current conveyor transconductance amplifier (CCTA), memristor and capacitor. Behaviour of the has been examined frequency range 0.6Hz to 6.4Hz with help simulations performed LTSPICE TSMC 180nm process parameters. It observed that area inside lobes reduces increase frequency. In comparison...

This paper presents a current re-use quadrature front end receiver architecture for ISM Band. The proposed architecture is a stacked QLMV cell which consists of a low-noise amplifier (LNA), mixer and voltage-controlled oscillator (VCO), which feeds into the intermediate frequency (IF) load. The LNA is a common source amplifier with Ls source degeneration, a double-balanced Gilbert cell mixer an...
