A novel architecture of digitally programmable continuous-time OTA-C filters

In this paper a very simple VLSI architecture of digitally programmable OTA-C filter is presented. The proposed realization uses a Digitally Programmable Transconductance Amplifier (DPTA) that permits to vary its transconductance parameter in digital way. Thus the tuning of many features of biquad section is obtained simply through digital control lines.
