title = "A Unity-Gain Buffer with 1.6GHz Bandwidth and 1900V/μs Slew Rate based on an OPA Adopting Cascaded Class-AB Structure",
abstract = "A wideband and high slew rate (SR) unity-gain buffer (UGB) with the capability to drive a heavy load is proposed in this brief. An operational amplifier (OPA) is configured as unity gain negative feedback to improve the bandwidth and gain accuracy. A complementary input stage and cascaded class-AB output stage are adopted to enhance the small-signal bandwidth and SR of the OPA. The UGB is implemented in the \$0.18-\textbackslash{}mu\textbackslash{}mathrm\{m\}\$ SiGe BiCMOS technology and achieves a -3 dB bandwidth of 1.6 GHz, and an average SR of \$1900\textbackslash{} \textbackslash{}mathrm\{V\}/\textbackslash{}mu\textbackslash{}mathrm\{s\}\$ with 5 V supply voltage and \$100\textbackslash{} \textbackslash{}Omega\$ load resistance. The quiescent current of the core amplifier is 3.8 mA.",
