- Abstract
In this paper, a new ultra-low-power double-inverter-based and multi-mode, high-order universal OTA-C filter is presented. The proposed circuit is designed based on the use of subthreshold biased double inverters as OTA blocks which leads to the reduction of power consumption as well as the chip size area. Furthermore, the grounded capacitors are employed in the proposed circuit to properly reduce the noise and parasitic effects of the proposed circuit. Moreover, another advantage of the proposed filter circuit is the low sensitivity of the proposed circuit performance to the values of the active and passive elements in the circuit. However, the proposed design is simulated in CADENCE using 0.18 µm CMOS technology parameters. As simulation results show, the proposed low-power filter has very good performance that can be considered as a proper universal OTA-C filter for ultra-low-power applications.
