The 741 and NE531 are bipolar types. The 741 is a popular general-purpose op-amp featuring internal frequency compensation and full overload protection on inputs and outputs. The NE531 is a high-performance type with very high slew rate capability; an external compensation capacitor (100pF) ...
Low Power Op-Amp Based on Weak Inversion with Miller-Cascoded Frequency Compensation A design for a rail-to-rail input and output operational amplifier is introduced. The circuit operates with 0.8 V single supply. The rail-to-rail input stage with controlled g/sub m/, is obtained by biasing...
It is also worth noting that this op amp is shown with five terminals, a number that happens to be a minimum for real devices. While some single op amps may have more than five terminals (to support such functions as frequency compensation, for example), none will ever have fewer. By ...
Internal Frequency Compensation Input and Output Overload Protected Pin Compatible with General Purpose Op Amps All trademarks are the property of their respective owners. The LM118 is a precision high speed operational amplifier designed for applications requiring wide bandwidth and high slew rate. It...
The op amp displays an input referred noise density of 58 and 8 nV/~ at 1 and 100 kHz frequencies, respectively. CONCLUSIONS An improved frequency compensation technique has been described with a brief review of the existing tech- niques. A CMOS implementation of the technique has also been ...
They are multiple pole systems, but they are internally compensated such that they appear as a single pole system over much of the frequency range. Internal compensation severely decreases the possible closed-loop bandwidth of the op amp. 展开 ...
An LM10, combined op amp and refer- ence, is used for the second amplifier and to provide the regulated voltage for offsetting the logging circuit and pow- ering the bias current compensation. Since a meter is the output indicator, there is no need to optimize frequency compensation. Low-...
The op amp frequency compensation was designed to opti- mize capacitive-load stability, slew rate and cross-over dis- tortion. The effective slew rate was increased from 2V/µs to 9V/µs by using two-pole compensation. The gain, phase and output impedance plots in Figure 4 characterize...
