Original Abstract

A new differential current amplifier is proposed which is based on a three current mirror topology. The amplifier shows superior performance compared to known circuits. The common mode rejection ratio (CMRR) of the amplifier can be optimized by properly predicting the aspect ratio of only one transistor. Simulation results agree with the theoretically expected.

Czech abstract

Je navržena struktura diferenčního zesilovače se třemi proudovými zrcadly. Zesilovač vykazuje výborné vlastnosti ve srovnání s dosavadními návrhy. Potlačení souhlasného signálu (common mode rejection ratio, CMRR) můžeme optimalizovat prostřednictvím jediného tranzistoru. Výsledky simulací ukazují soulad s teoretickými předpoklady.
