I should design an opamp transimpedance amplifier as homework, but i
have some doubts:
1) if current signal is an impulse (of positive value) generated every
10ms (for example), is it right to put the first pole of open loop
gain at frequency higher than (1/10)KHz?Or i shoud put the first pole
at frequency higher than 10(1/10)KHz (so the phase margin is equal to
180°)? I'm interested on voltage output (bacause this should be read
by an ADC)...
2)If i want to design an opamp with single supply, other problems
(respect to bipolar supply) are present or not?
Thanks
