Original Abstract

This paper presents a newly developed active device, referred to as a multiplied input differential difference amplifier (MIDDA), which allows operations of summation/subtraction and multiplication of input signals. It was designed and fabricated using I3T25 0.35 um ON (ON Semiconductor, Phoenix, AZ, USA) Semiconductor technology. The achieved results, which describe the experimentally verified behaviour of the fabricated device, are introduced, as well as the simple applications of MIDDA with electronically controllable parameters, useful for analogue signal processing. Moreover, the paper discusses an interesting example of nonlinear application to a double-sideband amplitude modulator, based on the utilization of multiplication and summation of particular signals. The laboratory experimental results which are achieved through the use of a fabricated prototype (both in time and frequency domain), confirm the workability of the concept.

Tento článek prezentuje nově vyvinutý aktivní prvek nazvaný zesilovač s násobením a součtově-rozdílovými operacemi (multiplied input differential difference amplifier - MIDDA), který dovoluje sečíst/odečíst a násobit vstupní signály dle definovaných vztahů. Prvek byl navržen v technologii ON Semiconductor I3T25 0.35 um. Získané výsledky popisují experimentálně ověřené chování vyrobeného zařízení stejně jako jednoduché aplikace MIDDA využívající elektronického řízení parametrů prvku. Mimo to článek rozebírá taktéž zajímavý příklad nelineární aplikace – AM modulátor s nosnou a oběma postranními pásmy, který je založen na využití dostupných operací násobení a sčítání specifických signálů. Laboratorní experimenty s vyrobeným prototypem v časové a kmitočtové oblasti potvrzují provozuschopnost konceptů.
