Abstract
In this paper, a novel digitally controlled CMOS balanced output transconductor (DCBOTA) is proposed. The digital control of the transconductance of this DCBOTA is achieved using novel current division network (CDN). The proposed DCBOTA operates under low supply voltage of ±1.5 V. Application of the DCBOTA is realizing variable gain amplifier VGA and second order active filter. PSPICE simulation confirms the performance of the proposed blocks and its applications.
