A 2.4GHz Low Power Highly Linear Mixer for Direct-Conversion Receivers
نویسندگان
چکیده
In this paper, a 2.4GHz low power downconversion mixer with high linearity for direct-conversion receivers based on a standard 0.18um CMOS technology is proposed. In the circuit design, Gilbert cell architecture and Common-Gate configuration are used. A simple buffer is applied in the IF output. Simulation results show that the mixer can operate at 2.4GHz and obtain the conversion gain of 11.08dB and the IIP3 of 13.64dBm. The return-loss and the noise figure (NF) are below -28dB and about 14dB, respectively. The low power highly linear mixer consumes around 3.96 mW from 1.8-V power supply. Key-Words: Mixer, Direct Conversion, Low Power, High Linearly, Receivers.

In this paper we present a new circuit design for a 2.4GHz CMOS direct conversion mixer incorporating adaptive offset cancellation. The basic circuit structure is that of a Gilbert cell mixer. Offsets are cancelled by dynamically varying the bias on the loads, which are designed to provide constant impedance independent of the load cancellation current. The bias control is regulated via an adap...

This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
