Abstract

A minimal CMOS low clamor speaker for Global Positioning System collectors is top to bottom examined and proposed in this paper. The outlined speaker works at particular 1.575 GHz GPS L-1 band recurrence, in this way a restricted band intensifier configuration approach is favored. Proposed configuration includes CMOS inverter circuit, one-sided to work experiencing significant change locale of activity, to give high pick up at a specific recurrence. To achieve better switch detachment, cascode outline systems are utilized. Reproduced execution shows transconductance gain of 19.94 dB, 1.74 dB Noise Figure with soundness factor more noteworthy than solidarity. The near investigation demonstrates that the proposed intensifier has practically identical execution with accessible GPS beneficiary ICs, made utilizing distinctive procedures, for example, GaAs and BiCMOS. This is very critical since the proposed configuration is comprised of minimal effort MOS gadgets as it were.

Keywords: CMOS Low noise amplifier, GPS, narrow-band, noise figure, S-parameters.
