“…Using the amplifier, the low voltage signal is converted to a high voltage signal. As described above, Biological signals are usually weak signals that need to be amplified, because signal processing is only possible with the high voltage signal [24]. The processor consists of an Analog to Digital Converter (ADC) which converts the analog to a digital signal for transmit the data to user.…”

A fully integrated, low-power, low-noise OTA for Biosensor is proposed in this paper to detect biomedical signal using Implantable Health Devices. The proposed Operational Transconductance Amplifier is built basedon differential mirror circuit. The existing IMD detects a single disorder and consumes high power resulting in need of replacement within a period of time. The output of the proposed OTA is validated under a balanced low supply voltage by means of simulation results using 180 nm, 90 nm and 45nmCMOS technology. The proposed OTA absorbs power within the range of nano watts. Comparison with the designs mentioned in the article is based on gain, noise, location, transconductance, and bandwidth. The findings indicate substantial performance and improvement of the proposed OTA is related to previously published designs that are suitable for biomedical applications. The post layout simulation of the proposed integrated circuit was successfully performed.

There is an advent need in health industry, for an Implantable Medical Device (IMD) withlower power consumption, noise and area as much as possible, which aims at extending the life-span of the device by enhancing the performance of battery to avoid additional surgery and does not affect the tissue cells. The existing IMD detects a single disorder and consumes high power resulting in need of replacement within a period of time. Furthermore there is a sheer need to reduce the noise factor to achieve an uninterrupted signal. This paper proposes a novel Operational Transconductance Amplifier (OTA) which is used in the biosensors of IMD. The proposed OTA is designed in a 0.18 μm CMOS (Complementary Metal Oxide Semiconductor) technology, the operational frequency is in the range of 0.36 Hz to 50 KHz and capable of measuring the gain in 60 dB. It consumes a negligible amount of (5 μW) power per OTA from 1-V single power supply and achieves minimal input referred noise of 1.24 μVrms, which is highly acceptable for biosensor used in IMD. The post layout simulation of the proposed integrated circuit has been performed successfully.

Health care industries are progressing towards improving the health condition of the society, by developing new medical devices with innovative technologies. The advancement in medical technology has brought to reality developing sensor-based medical devices, which are implantable as well as wearable. The present challenge is designing in terms of low noise, low power, low area design techniques, considering patient safety and for a long term process these devices are getting more prevalent in the society. Addressing the problem of battery drain in Implantable Medical Devices (IMD) to the replacement of IMDs and additional surgeries would be the solution due to that. This survey paper presents a glimpse of a deep survey done on various types of power approaches that are carried out on Implantable Medical Devices focusing on extending their durability and attempts done to design various types of amplifiers and converters for sensors used in different medical devices.
