| Popis: | Summary A new solution for an ultra low voltage bulk-driven programmable gain amplifier (PGA) is described in the paper. While implemented in a standard n-well 0.18-µm complementary metal–oxide–semiconductor (CMOS) process, the circuit operates from 0.3 V supply, and its voltage gain can be regulated from 0 to 18 dB with 6-dB steps. At minimum gain, the PGA offers nearly rail-to-rail input/output swing and the input referred thermal noise of 2.37 μV/Hz1/2, which results in a 63-dB dynamic range (DR). Besides, the total power consumption is 96 nW, the signal bandwidth is 2.95 kHz at 5-pF load capacitance and the third-order input intercept point (IIP3) is 1.62 V. The circuit performance was simulated with LTspice. Copyright © 2016 John Wiley & Sons, Ltd. |
