Abstract:
A circuit for providing a limited amplifier output, comprising:a first source of a first signal;a first amplifier having a first input and a first output, said first input being connected in electrical communication with said first source;second amplifier having a second input and a third input, said second amplifier having a second output, said second output being connected to said first input, said third input being connected to said first output, said second amplifier being a current sourcing comparator and said second output being connected to provide a current to said first input to prevent an increase in the magnitude of said first output;a second source of a reference signal;first means for providing a second signal which is a first preselected percentage of said reference signal, said second signal being connected to said second input; andsecond means for providing a third signal which is a second preselected percentage of said first output signal, said third signal being connected in electrical communication with said third input, said first output signal being limited to a magnitude which is generally equal to said reference signal multiplied by the ratio of said first and second preselected percentages;wherein:said-first providing means comprises a first voltage divider; andsaid second providing means comprises a second voltage divider.
