One of error correction amplifier (opamp based)
I seen this schematic from simple car amplifier (only invert opamp based input) but I change it's input to instrumentation differential input (somebody whom posted) which compare (input+feedback)--->(original input) and then bring signal after compare to invert opamp for drive transistor drive & output.
Thanks analog guy |

Other schematic
I quite interested about Common Collector Output Transistor, such as crescendro V2.It's also used opamp based power amplifier but I'll insert my input stage opamp (invert+non invert instrumentation input schematic) into crescendro...How about ?
Please suggest me Thanks analog guy |
