This paper presents an application of operational transconductance amplifiers (OTA), namely a simulated resistance made with OTA. Its value can be controlled by the current polarization of the operational transconductance amplifier. It is also presented an immediate application of the simulated resistance, namely the low-pass filter.
Today, the waste represents one of the most serious issues of the environment protection. Annually big amount of waste is generated. Economic operators can exploit various types of waste, which may be treated, recycled or can be routed to a treatment plant (for reducing degree of nuisance) or to an incinerator (for reducing the volume). Unused waste is, as a general rule, stored. In this case study,...
This paper proposes a systematic approach of second order current-mode RC oscillators (CMO-RC) and the study of the errors introduced by these oscillators. The generation is done by current amplifying active blocks whit a single input and two opposing outputs (SIDO) and standard current amplifiers (a single input and a single output). This solution of using one input — two outputs current amplifiers...
This paper proposes an application of the current using its advantages in harmonic signals generation. Using current-conveyors in harmonic oscillators building, the frequency band of active device is well valorised, comparing with the situation of operational amplifiers using. The author chooses from all RC oscillators the oscillator with Wien network, as one of the most used net for RC oscillators...
