Yesterday, 20:17Hi, Why the zeners across GS? The drive voltage is 15Vmax and the Mosfets can widthstand 20V. I see no reason for the zeners ... also zeners...5 replies | 192 view(s) -

Yesterday, 16:15Hi, a common mode choke may be very high impedance for common mode signals, but it may be very low impedance for differential mode signals. You...3 replies | 114 view(s)

14th December 2019, 10:36Hi, With "input" I meant the signal in your circuit that is marked "Vin". And yes it goes to the inverting input of the amp. Note: In your...10 replies | 368 view(s)

13th December 2019, 22:00Hi, Yes you miss the characteristic impedance. You just need to drive the 75 Ohms of the cable impedance, that's it. This already includes the...8 replies | 311 view(s)

13th December 2019, 16:07Hi you missed the brackets: ((5V7-V_in-v_d1)*R2/(R1+R2))/R2 then you may simplify it: --> ((5V7-V_in-v_d1)*R2/(R1+R2))/R2 -->...4 replies | 236 view(s)

13th December 2019, 15:38KlausST replied to a thread [SOLVED] Transformers on a PCB in Hobby Circuits and Small Projects ProblemsHi, We are talking about HF. Thus this still is far away from being a GND plane. All the traces have the same length as before ... and for HF...10 replies | 435 view(s)

13th December 2019, 12:34KlausST replied to a thread [SOLVED] Transformers on a PCB in Hobby Circuits and Small Projects ProblemsHi, It does not depend on whether your circuit produces HF or not, it depends whether your circuit reacts on HF. And this depends on what exactly...10 replies | 435 view(s)

13th December 2019, 12:23Hi, we have more modern ones like JBC for example, but I can see no benefit against the "old ones". They claim about longer tip liefetime - but...7 replies | 315 view(s)

13th December 2019, 12:06Hi, according ohm´s law. 5V input will give 50uA, this is half of 100uA. So this should be linear. Nobody can tell whether your meter works...6 replies | 173 view(s)

12th December 2019, 18:42Hi, A2 has a defined gain of -1, thus it should work. A1 has an input impedance of 1600 Ohms @ 1kHz (C7). This causes a gain of -32 @ 1kHz. But...10 replies | 368 view(s)
