Abstract-This paper presents a detail on various techniques to realize low voltage low power circuit. The techniques discussed are conventional gate-driven (GD), floating gate (FG), quasi-floating gate (QFG), bulk-driven (BD), and BD-QFG. The comparative analysis results in best performance achieved by BD-QFG approach. As BD circuits are well known approach for low power design, the combined effect QFG in bulk driven circuit results in enhanced performance. The complete analysis has been carried out in industry specific node UMC 0.18 micron technology with the help of HSpice simulator.

“…Methods for effective optimization of a recording channel in terms of its power consumption, input-referred voltage noise, silicon area, and technology used are discussed in [40]. The design of nanopower OTAs with enhanced linearity is presented in [41]. In the case of recording from a multielectrode array, the total power consumption of the amplifier array (as well as the silicon area) may be reduced by using the partial OTA sharing structure proposed in [42].…”

Implantable medical devices provide therapy to treat numerous health conditions as well as monitoring and diagnosis. Over the years, the development of these devices has seen remarkable progress thanks to tremendous advances in microelectronics, electrode technology, packaging and signal processing techniques. Many of today's implantable devices use wireless technology to supply power and provide communication. There are many challenges when creating an implantable device. Issues such as reliable and fast bidirectional data communication, efficient power delivery to the implantable circuits, low noise and low power for the recording part of the system, and delivery of safe stimulation to avoid tissue and electrode damage are some of the challenges faced by the microelectronics circuit designer. This paper provides a review of advances in microelectronics over the last decade or so for implantable medical devices and systems. The focus is on neural recording and stimulation circuits suitable for fabrication in modern silicon process technologies and biotelemetry methods for power and data transfer, with particular emphasis on methods employing radio frequency inductive coupling. The paper concludes by highlighting some of the issues that will drive future research in the field.

“…OTA is an important building block for analogue circuits [1][2][3][4] and widely used in low power applications such as biomedical signal processing [5,6]. OTA for biomedical analogue front-end determines the performance of the circuit, such as power consumption, supply voltage, noise, and linearity [1,[6][7][8][9]. In biomedical applications, the use of low voltage and low power are highly desirable [6,10].…”

This study presents a new technique based on large signal analysis, to enhance the total harmonic-distortion (THD) in an ultra-low-power operational transconductance amplifier (OTA). The proposed technique is used to implement an ultra-lowpower gate-driven and bulk-driven OTA with high linear range. Mismatch and post-layout simulations in 0.13 μm CMOS technology demonstrate that the proposed technique can improve the THD and the dynamic range, without affecting the transconductance tuning and the common-mode control. It achieves a 183 and 640 mVpp linear ranges for gate-driven and bulk-driven OTA, and a 61.8 dB dynamic range at 0.5 V with 26.35 nW power dissipation.
