The voltage-amplifier stage (or VAS) has often been regarded as the most critical part of a power-amplifier, since it not only provides all the voltage gain but also must deliver the full output ...

Although I used op amps in many feedback loops over the years, the subject of transconductance op amps versus voltage feedback op amps has always intrigued me. Therefore, I thought it would be a good ...

Capable of operating on +3V, +5V or ±5V, the AD8091 (single) and AD8092 (dual) high-speed voltage-feedback amplifiers are ideally suited for use in portable and battery-operated applications, ...

Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...

Until now, very high-speed Operational Amplifiers (OP AMPS) have offered a top bandwidth of about a gigahertz. The addition of silicon germanium (SiGe) to a high-speed bipolar-CMOS process results in ...
