WebBy definition, a guard trace is a trace routed coplanar between an aggressor line and a victim line. Often the guard trace is terminated at each end in its characteristic impedance or shorted to ground. WebSep 19, 2024 · Even though your guard trace surrounds the input node, you'll want to reduce any capacitance between it and the input. Otherwise, you'll hurt your amplifier's frequency response; R2 will cause a slight voltage difference between your guard ring and your input (TIP), which could cause current to leak directly from your input to your guard …
