How to Reduce Electromagnetic Effects in PCBs

Avoid adding additional wire to the parasitic resonant tanks of the power loop. Unfortunately, this eliminates the possibility of using a current probe to simultaneously measure the switching current.

Avoid PC-Layout 'Gotchas' in ISM-RF Products Tutorial

The feedback through the parasitic Cfb is limited by the plate resistance of the second triode, maybe the 37.5K of a 12AX7, and is divided down by the other capacitances at the grid of the first triode, Cgeq, and by any loading at the input other than the grid leak resistor. Let's take worst case, the input open.

Avoid PC-Layout "Gotchas" in ISM-RF Products Tutorial

Disconnect the positive battery cable and, with the meter set to the DC volts setting, take a voltage reading between the battery terminal and the cable. If it reads 12 volts — or any voltage, really — you have a leak.

Avoiding MOSFET Driver Overstress Microchip Technology

Figure 5 shows a typical op amp circuit as it appears on the schematic, and real-world circuit on a PCB; every pad adds a parasitic capacitor, and every trace adds a parasitic inductor. Just for fun, resistors, capacitors, and inductors are far from ideal and each one adds its own set of parasitics to the mix.

Modeling and Analysis of the Effects of PCB Parasitics on

disturbance occurs on the track A the Transil P clamps the surge at a maximum voltage V CL and thus protects the sensitive part. During this clamping action there is a current through P and also in the track A. This phenomenon induces a voltage on track B, where it is close to A. To avoid this undesirable parasitic overvoltage on track B, the circuit of Figure 2 is recommended. Figure 2

AN3303 Application note Farnell element14

Winding Voltage for Biasing the NCP1602 CSZCD Pin NCP1602 combines the current sense (CS) and the core demagnetization detection (ZCD, zero crossing detection) signals into a single pin named CSZCD. In some noisy environment, a non-optimum choice of sensing resistors combined with a dense PCB layout can lead to a unstable operation of 1602. In this particular situation, the adoption of a …
