Abstrakt

Low noise amplifier (LNA) is terribly important block in designing broadband receivers for wireless broadband communications. Being the primary active element in receiver chain it creates larger demand for LNAs that are smaller, consume less power, and provide sufficient gain, low noise and high compact design [1–14]. The projected LNA is extremely integrated with low noise figure having wide calibration range with improved RF power handling system and acquires less space on chip. Previous work mainly focused on the reduction of noise and power consumption [1–14]. But due passive component resistor, the problem of area for design was still there. The reduction in area of chip is proposed in this paper by using switched capacitor. Switched capacitor resistor is used in place of regular resistor and MIM capacitor in place of regular capacitor. The operating frequency of the projected LNA is from 0.8 to 2.9 GHz as during this frequency range high speed operations like GPS, UMTS, GSM Bluetooth and Wi-Fi are covered. MIM capacitor is placed in multi customary cascade common supply (CS-LNA). The steady state is additionally calculated by frequency domain methodology i.e. harmonic balance response analysis is additionally done. The design is implemented in cadence IC virtuoso using 180 nm CMOS technology. The simulated results show the reduction within the noise figure and also the feasibility of LNA with MIM capacitor and switched capacitor attributable to that area on chip is reduced, steady state in frequency domain is additionally calculated by harmonic balance response analysis.   Keywords: LNA, multi-standard, RF, MEMS, noise figure, common source(CS), passive component Cite this Article Nishant Poras, Priyanka Goyal.
