This paper presents a negative type secondgeneration current conveyor (CCII-). It is based on an inverter-based low-voltage error amplifier, and a negative current mirror. The CCIIcould be operated in a very low supply voltage such as ±0.5 V. The proposed CCIIhas wide input voltage range (±0.24 V), wide output voltage (±0.24 V) and wide output current range (±24 mA). The proposed CCIIhas no on-...

This paper presents a new CMOS fully differential second-generation current conveyor (FDCCII). The proposed FDCCII is based on a fully differential difference transconductor as an input stage and two class AB output stages. Besides the proposed FDCCII circuit is operating at supply voltages of ± 1.5 V, it has a total standby current of 380 μA. The application of the FDCCII to realize variable g...

This paper describes the architecture of first and second generation current conveyor (CCI and CCII respectively) and designing an amplifier using second generation current conveyor. The designed amplifier through CCII+ can be used in various analog computation circuits and is superior in performance than the classical opamp. It provides better gain with higher accuracy.

Large bit-line capacitance is one of the main bottlenecks to the performance of on-chip caches. New sense amplifier techniques need to explicitly address this challenge. This paper describes two sensing techniques to overcome this problem: a current sense amplifier (CSA) and a charge transfer sense amplifier (CTSA) and their implementation based on 90nm CMOS technology. The current sense amplif...

The need for high speed, wideband amplifiers is the driving force behind the development of the Current Feedback Amplifier (CFA). The CFA has significant advantages over conventional amplifiers in terms of slew rate performance and inherently wide bandwidth. This paper provides a review of the theory and design of current feedback amplifiers.

It is well known that a °oating inductor circuit is realized from a grounded inductor circuit by replacing the operational ampli ̄er by a °oating operational transconductance ampli ̄er. This idea is extended to transform current conveyor grounded inductors to °oating inductors by replacing the current conveyor by the recently introduced °oating current conveyor. Several examples are considered an...

Performance of sense amplifier has considerable impact on the speed of caches used in microprocessors. The small difference in voltage level of bit lines of memory cell is amplified by sense amplifier. voltage mode sense amplifier reduces the power dissipation during read and increases the speed also.
