This paper presents a fully integrated bluetooth low energy (BTLE) receiver front-end implemented in 0.13 um CMOS including the low noise amplifier (LNA), mixer and a variable bandwidth complex bandpass filter. The measured current consumption of the complete front-end is only 2.7 mA at 1.2 V. The designed front-end provides a voltage gain of 40 dB, a noise figure of 11 dB and a IIP3 of −21.2 dBm...
This paper presents a continuous-time quadrature bandpass ΔΣ ADC that achieves 60dB DR and 67.4dB SFDR at 1MHz BW and 1MHz IF. The modulator uses capacitive feedforward architecture for the 3rd order loop filter for reduced power consumption and a local feedback loop for optimized noise shaping within the required band. The design is targeted for low power low IF receivers and it achieves a total...
This paper presents a novel demodulator architecture for short distance communication application with low effort, which is low-power low-cost while achieving robust and sufficient performance. Compared to other architectures, power consumption and design complexity are significantly reduced. Practical issues such as image interference, group delay and frequency offset are compensated and calibrated...
Insufficient image-rejection due to I/Q mismatch considerably degrades the performance of modern wireless communication systems. This paper presents a SystemC-AMS front-to back-end modeling approach in a Low-IF receiver system with a digital adaptive filter for I/Q mismatch compensation. With the proposed approach, the non-ideal behavioral of the analog building blocks concerning I/Q imbalance is...
