A 2-6 GHz WiMAX Low Noise Amplifier (LNA) using active inductor as shunt peaking load in resistive feedback configuration is designed in 0.13-μm CMOS process. This low noise amplifier uses a single active inductor to achieve high gain and input matching which leads to a compact circuit. The simulations show a maximum power gain (S21) of 14.18dB, minimum noise figure (NF) of 2.44dB while the input...
A low-voltage and high-linearity downconverter RFIC design using TSMC 0.18 μm CMOS foundry for WiMAX applications is presented in this paper. The LC resonator is used to block DC and RF signals for low supply voltage and the multiple-gated CMOS is adopted to eliminate third-order nonlinear term for high linearity. The crucial simulated results of WiMAX downconverter include that a conversion gain...
An integrated 6.2-9.5GHz CMOS UWB receiver for WiMedia MB-OFDM is proposed. The fully differential receiver consists of a wideband LNA and a down conversion mixer with high and low gain mode. A low-pass filter and a programmable gain amplifier are also included. The chip was fabricated in TSMC 0.13-μm RF CMOS process. Measurement results show that the receiver achieves voltage gain from 21dB to 63dB...
A low power high linearity folded mixer for 3.6 GHz WiMAX application is presented in this paper. The circuit was designed with TSMC 0.18μm CMOS process. An RF PMOS is used to improve the linearity. The proposed folded mixer has the conversion gain of 4.4dB with LO power at -5dBm. The IIP3 is 5.5dBm, noise figure is 11.6dB, and the power consumption is 2.636mW without output buffer. The total power...
A 24 GHz quadrature receiver front-end in 90-nm CMOS is presented. It consists of a two-stage LNA, passive mixers, and a QVCO. The RF input is single-ended and is converted to differential form in the first LNA stage. The LNA has two bands of operation within the frequency range of the QVCO. The oscillator measures a centre frequency of 23.7 GHz with a 7.2% tuning range, a worst case phase noise over...
