Special Issue Information

Dear Colleagues,

Traditional biomedical devices operate with batteries in vivo. The use of a battery necessitates the large footprint of the device and determines its limited life-time. Thus, biomedical device realized with a small foot-print integrated circuit (IC) empowered by wireless power transfer have proven to be useful, but the reported (earlier) works have seen limited performances in the amount of available power in vivo, biosafety, data rate, and energy efficiency of biotelemetry.

This Special Issue aims to highlight the development of mimiaturized, biomedical sensors improving the scalability of the system and energy efficiency. Topics include but are not limited to the following:

  • autonomous operation;
  • biomedical implants;
  • biomedical sensor;
  • energy harvesting;
  • fully integrated system;
  • implantable device;
  • integrated circuits;
  • low power transceiver;
  • sensor interface;
  • wireless power transfer

In this work, a new versatile voltage- and transconductance-mode analog filter is proposed. The filter, without requiring resistors, employs three differential-difference transconductance amplifiers (DDTAs) and two grounded capacitors, which is suitable for integrated circuit implementation. Unlike previous works, the proposed filter topology provides: (1) high-input and low-output impedances for a voltage-mode (VM) analog filter, that is desirable in a cascade method of realizing higher order filters, and (2) high-input and high-output impedances for a transconductance-mode (TM) analog filter without any circuit modification. Moreover, a quadrature oscillator is obtained by simply adding a feedback connection. Both VM and TM filters provide five standard filtering responses such as low-pass, high-pass, band-pass, band-stop and all-pass responses into single topology. The natural frequency and the condition of oscillation can be electronically controlled. The circuit operates with 0.5 V supply voltage. It was designed and simulated in the Cadence program using 0.18 µm CMOS technology from TSMC. Full article

This paper demonstrates the advantages of the multiple-input transconductor (MI-Gm) in filter application, in terms of topology simplification, increasing filter functions, and minimizing the count of needed active blocks and their consumed power. Further, the filter enjoys high input impedance, uses three MI-Gms and two grounded capacitors, and it offers both inverting and non-inverting versions of low-pass (LPF), high-pass (HPF), band-pass (BPF), band-stop (BS) and all-pass (AP) functions. The filter operates under a supply voltage of 0.5 V and consumes 37 nW, hence it is suitable for extremely low-voltage low-power applications like biosignals processing. The circuit was designed in a Cadence environment using 180 nm CMOS technology from Taiwan Semiconductor Manufacturing Company (TSMC). The post-layout simulation results, including Monte Carlo and process, voltage, temperature (PVT) corners for the proposed filter correlate well with the theoretical results that confirm attractive features of the developed filter based on MI-Gm.
