Implantable Biomedical Devices

Implantable biomedical devices (IBDs) play a vital role in today’s healthcare industry. Such applications demand high data rate, low power and small-sized demodulators. This work presents a simple small-sized low-power architecture for differential quadrature phase shift keying (DQPSK) demodulator for these devices. The proposed circuitry is designed in UMC 90-nm CMOS technology and occupies a layout area of 0.015[Formula: see text]mm2. It is operated at 1-V supply voltage with a power consumption of 405[Formula: see text][Formula: see text]W. The carrier frequency is 10[Formula: see text]MHz and the obtained data rate is 20[Formula: see text]Mbps. Hence it exhibits a high data-rate-to-carrier-frequency (DRCF) ratio of 200% making it ideal for IBDs.

Abstract A 400 MHz high efficiency transmitter for wireless medical application is presented in this paper. Transmitter architecture with high-energy efficiencies is proposed to achieve high data rate with low power consumption. In the on-off keying transmitters, the oscillator and power amplifier are turned off when the transmitter sends 0 data. The proposed class-e power amplifier has high efficiency for low level output power. The proposed on-off keying transmitter consumes 1.52 mw at -5 dBm output by 40 Mbps data rate and energy consumption 38 pJ/bit. The proposed transmitter has been designed in 0.18μm CMOS technology.
