Abstract :
A low-power 435 MHz differential low-noise amplifier with on-chip spiral inductors was implemented in a 0.5 μm standard CMOS process. The LNA is intended for use in a low-power low-IF receiver under development for deep space communication. A current reuse technique is employed for low-power operation. Low-noise layout techniques are used to improve the noise performance. Design trade-offs to achieve low-power and low-noise at UHF frequencies are addressed. The LNA has a noise figure of 0.94 dB, input 1 dB compression point of -32 dBm, input third-order intercept point of -27 dBm and forward gain of 25 dB. The active area of the LNA is 1.3 mm×1.1 mm.
