“…12. As it is easy to note, the proposed filter offers the best FOM, which is approximately one order of magnitude better than achieved for the design in [16], which was supplied with the same VDD. The most similar FOM was reported for the filter in [5], however, that circuit was supplied with much larger VDD.…”

“…Table IV presents a comparison of the proposed filter with other similar designs of biopotential filters, published in recent years. First of all is worth noting, that the proposed filter can operate with much lower VDD than other filters in Table IV, except [16]. Despite its single-ended architecture and ULV supply, the filter offers the best dynamic range among all the compared filters.…”

This paper presents a compact power-efficient CMOS fourth-order low-pass filter suitable for electrocardiogram (ECG) acquisition systems. The CMOS structure of the proposed filter utilize the bulkdriven technique and operates in subthreshold region to achieve extremely low-voltage supply (0.3V) and nanopower consumption (0.676 nW) for cutoff frequency of 100 Hz. The filter was designed and simulated using 0.18 µm CMOS TSMC technology. The total input referred noise of the filter is 87 µVrms and the dynamic range is 58.1 dB. The filter offers the best figure of merit of 2.91 x 10-14 J, the lowest power consumption and voltage supply, compared with the previous state-of-the-art nanowatt filter designs.

“…The analog low-pass filters for ECG acquisition systems should be designed to meet specific requirements, such as high dynamic range, low-power consumption, and small chip area. There are many low-pass filters for ECG acquisition systems described in the literature [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. The Butterworth approximation is usually used because it provides a better linear phase and flat response within each bandwidth.…”

This paper presents a 0.5 V fifth-order Butterworth low-pass filter based on multiple-input operational transconductance amplifiers (OTA). The filter is designed for electrocardiogram (ECG) acquisition systems and operates in the subthreshold region with nano-watt power consumption. The used multiple-input technique simplifies the overall structure of the OTA and reduces the number of active elements needed to realize the filter. The filter was designed and simulated in the Cadence environment using a 0.18 µm Complementary Metal Oxide Semiconductor (CMOS) process from Taiwan Semiconductor Manufacturing Company (TSMC). Simulation results show that the filter has a bandwidth of 250 Hz, a power consumption of 34.65 nW, a dynamic range of 63.24 dB, attaining a figure-of-merit of 0.0191 pJ. The corner (process, voltage, temperature: PVT) and Monte Carlo (MC) analyses are included to prove the robustness of the filter.
