<p>Embodiments of the present disclosure provide input termination circuits that overcome the deficiencies of conventional designs. Specifically, embodiments eliminate large-on chip bypass capacitors that are commonly used for common mode termination, and instead use an active capacitor-multiplier (C-multiplier) circuit at the common mode node. The C-multiplier circuit mimics a large capacitor at high frequency. By eliminating large on-chip bypass capacitors, the IC design (e.g., receiver) is reduced in size, without affecting common mode return loss performance. Embodiments may be used with any applications that require input termination, and particularly with differential applications that require common mode termination.</p> |
