Current-mode ladder filters using multiple output current conveyors

IEE Proceedings - Circuits, Devices and Systems, 1996
A methodology to design continuous-time current-mode filters using current conveyors is presented. A multiple output current conveyor (MOCC), which contains both the positive and the negative outputs, is introduced. Based on the simulation of the passive RLC ladder prototypes, current-mode ladder filters using MOCCs are obtained.

A current switch of current-steering DAC output stage

2011 IEEE International Conference on Anti-Counterfeiting, Security and Identification, 2011
When DAC is applied to communication field, it is generally necessary to have a good dynamic performance. However, nonlinear distortion of output stage current switch has a potent effect on DAC as a whole. The approach proposed in this paper aims to improve on distortion in output stage.

Current-mode oscillators using single output current conveyors

Microelectronics Journal, 1998
It is shown that the voltage-mode oscillators employing noninverting or inverting voltage controlled voltage sources can be transformed directly to current-mode oscillators by element replacement technique and using composite current conveyors. Examples of the Wien oscillator and the phase shift oscillator together with PSpice simulation results are ...

Class AB differential input/output current-controlled current amplifier

2013 International Symposium on Intelligent Signal Processing and Communication Systems, 2013
A new CMOS-based class AB differential input/output current-controlled current amplifier is described. The design technique is achieved by the combination of a class AB squaring circuit and current mirrors. The current amplifier has features of linear current gain controllability and low power consumption. Its current gain can linearly and electrically

Sinusoidal oscillators with explicit current output employing current‐feedback op‐amps

International Journal of Circuit Theory and Applications, 2008
AbstractEmploying a state‐variable synthesis, a number of new current‐mode oscillators with explicit current output have been derived, which can be practically implemented from commercially available current‐feedback op‐amps (CFOA). The workability of the proposed structures has been confirmed by experimental results using AD844‐type CFOAs and some ...

SQUID Current Sensor With Differential Output

IEEE Transactions on Applied Superconductivity, 2013
We have developed a superconducting quantum interference device with differential output (diffSQUID). The device concept aims at improving the operability of SQUID current sensors in the presence of large common-mode signals. The diffSQUID is based on a series connection of two identical SQUID sensors. The biasing and input signal coupling provides for

Output Current Ripple-Free PWM Inverters

IEEE Transactions on Circuits and Systems II: Express Briefs, 2010
In this brief, a simple modular passive ripple mirror circuit (PRMC) is proposed for eliminating the inherent high-frequency current ripple of pulsewidth modulation (PWM) inverters. The proposed passive circuit is robust in the sense of without containing either any power semiconductor switch or any extra control.

Current-fed multiple-output power conversion

Nineteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2004. APEC '04., 2004
This paper focuses on low cost and low component count, multiple-output power conversion. The work is particularly applicable to both isolated and nonisolated conversion to multiple independently regulated low voltage outputs. The topology employed is a switch-mode current source feeding interleaved switched capacitor outputs.

Modeling Analog Sun Sensor Current Output

Proceedings. The First IEEE Regional Conference on Aerospace Control Systems,, 2005
This paper presents the derivation of a new sun sensor model and compares the predicted output to unit test data. The new model has been derived for a generalized rotation of the sensor with respect to the principal axes of the spacecraft. The modeling of the variation of the space output as a general function of the kinematics of the rotation of the ...
