Nowadays in Modern wireless Receiver, high speed data availability and increased usage of wireless devices has increased challenges in improving battery life. In voltage mode circuits shows poor performance in various parameter like gain, bandwidth, power consumption. To overcome of this disadvantage current mode are much more beneficial. Due to exponential increase in users, bandwidth requirement also increased. In any communication system, current mode receiver will be beneficial from high data rate receiving point of view. In this paper, a current mode receiver which can operate at very low voltage and provide high frequency at the output. For this, a current-mode device is modeled and using this modeled device, the various circuit blocks are simulated using H-SPICE software. The proposed current mode receiver can work at very low voltages and consume less power, compare to voltage mode receiver.
