Design of Fully-Differential Filtering Structure with Adjustable Current Amplifier
MetadataShow full item record
The contribution deals with design and analysis of controllable second-order frequency filter which operates in the current mode and where the main element is the current amplifier DACA (Digitally Adjustable Current Amplifier) and also MOTA (Multiple Output Transconductance Amplifier) is used. The paper presents a description of the proposed circuit and results of computer simulations for circuit in single-ended and fully-differential variant. Four simulation models with different properties were used for simulating of the DACA active element in the proposed circuit.
