Abstract:This paper presents the design and optimization of a parametric multiple-channel Double Dynamic Switching Biased Complementary Folded-Cascode Amplifier with switched capacitor integrator application in 32nm FinFET technology. The LTspice simulations demonstrate that the amplifier can attain an open-loop DC gain of 44.8dB, and a phase margin of about 87.8° with ±0.5V supply voltages. Moreover, the amplifier power consumption is measured 246µW including bias circuitry and a Gain-Bandwidth Product (GBW) of 77.45MHz under a 5pF load capacitor. The circuit’s stability enables it to offer diverse design capabilities tailored to specific application needs. This novel design is capable of reducing supply voltages and power dissipation

Title:Načrtovanje in optimizacija večkanalnega dvojnega dinamičnega preklopnega optičnega ojačevalnika za stikalni kondenzatorski integrator z uporabo tehnologije FinFET
Abstract:Članek predstavlja načrtovanje in optimizacijo parametričnega večkanalnega ojačevalnika z dvojnim dinamičnim preklopom, ki se opira na komponente z zloženo kaskodo, z uporabo integratorja s preklopnim kondenzatorjem v 32 nm tehnologiji FinFET. Simulacije LTspice kažejo, da lahko ojačevalnik doseže ojačenje z odprto zanko DC 44,8 dB in fazno rezervo približno 87,8° pri napajalnih napetostih ±0,5 V. Poleg tega je izmerjena poraba energije ojačevalnika 246 µW, vključno z napajalnim vezjem in GBW 77,45 MHz pri obremenitvenem kondenzatorju 5pF. Stabilnost vezja omogoča diverzno načrtovanje s prilagoditvami glede na potrebe aplikacije. Ta nova zasnova lahko zmanjša napajalne napetosti in porabo.
Keywords:32nm FinFET tehnologija, komplementarni kaskodni ojačevalnik, dvojno dinamično preklapljanje polarizacije, preklopni kondenzator
