Ultra-low power BPSK demodulator for bio-implantable chips
A novel non-coherent binary phase shift keying (BPSK) demodulator featuring ultra-low power and high data rate is presented for inductively powered biomedical implants. The circuit is designed in the 0.18μm standard CMOS technology. Simulation results show that at a data transmission rate of 16Mbps, the power consumption of the circuit is as low as 6.3μW and 1.96μW at a supply voltage of 1.8V a...
متن کاملAn FSK and OOK Compatible RF Demodulator for Wake Up Receivers
This work proposes a novel demodulation circuit to address the implementation of Wake-Up Receivers (Wu-Rx) in Wireless Sensor Nodes (WSN). This RF demodulator, namely Modulated Oscillator for envelOpe Detection (MOOD), is compatible with both FSK and OOK/ASK modulation schemes. The system embeds an LC oscillator, an envelope detector and a base-band amplifier. To optimize the trade-off between ...
متن کاملAn FSK Demodulator Design for RF Wireless Sensor Applications Using Zigbee Protocol
In this paper, transistor-level simulations of a detector called “cross-differentiate-multiplier demodulator (CDM)” are presented. This detector, which uses three blocks (a differentiator, a multiplier and a subtractor), is able to demodulate a received bit sequence, that was transmitted using a frequency-shift keying modulation scheme, with a bit rate equal to 20kbps. The application of this d...
متن کاملPerformance of Post-Demodulator Adaptive Filters for FSK Signals in a Multipath Environment
FSK continues to be an important component of modern communication systems, and discoveries of lower impact methods for mitigating performance degradation due to multipath propagation are needed in many application areas. Previous work suggested the benefit of a simple post-demodulator LMS filter but the focus was narrow and analysis was hindered by the nonlinearity of the demodulation process ...
متن کاملA 60-GHz LTCC SiP with Low-Power CMOS OOK Modulator and Demodulator
In this paper, a 60 GHz LTCC SiP with low-power CMOS OOK modulator and demodulator is presented. The 60 GHz modulator is designed in a 90-nm CMOS process. The modulator uses a current reuse technique and only consumes 14.4-mW of DC power in the on-state. The measured data rate is up to 2 Gb/s. The 60 GHz OOK demodulator is designed in a 130nm CMOS process. The demodulator consists of a gain boo...
