Abstract
A re-circulating amplifier comprising a SAW filter with group delay characteristics for providing a time delay function.
Claims12
A re-circulating amplifier comprising:
- a SAW filter with group delay characteristics, said characteristics providing a time delay function;
- and
- a sampling amplifier for sampling an input signal, wherein said input signal passes three times through said further amplifier and SAW filter to provide high net gain.
A re-circulating amplifier comprising:
- a SAW filter with group delay characteristics, said characteristics providing a time delay function;
- a sampling amplifier for sampling an input signal;
- and
- a further amplifier associated with said SAW filter for re-circulating said input signal, wherein switching waveforms of said sampling amplifier and said further amplifier do not overlap.
