MT-033 For example, if we have an application which requires a closed-loop gain of 10 and a bandwidth of 100 kHz, we need an op amp with a minimum gain-bandwidth product of 1 MHz. This is a slight oversimplification, however, because of the variability of...

anonymous Op Amp Radio Thursday, October 17, 2013 3:30:11 PM I built a similar radio many years ago, using a mosfet opamp from RS, a TL 7611 I think. Feedback resistor was 100M ohm! So powerful on 1.5v, it didn't need external antenna! advisor Op Amp ......
