Abstract:
1. A programmable circuit comprising: a first coil for transmitting an input signal; a high impedance path having a first node connected to a first node of the first coil; a low impedance path having a first node connected to the first node of the first coil, the low impedance path connected in parallel with the high impedance path; a capacitive path having a first node connected to a second node of the first coil, the capacitive path forming a circuitous path with the high impedance path and the low impedance path; an input path for coupling signals into the high impedance path, the low impedance path, and the capacitive path, a second coil having a first node and a second node, the second coil being inductively coupled to the first coil; a switch having a first node and a second node, the first node of the switch being connected to the first node of the second coil; and a resistive element having a first node and a second node, the first node of the resistive element being connected to the second node of the switch, the second node of the resistive element being connected to the second node of the second coil, wherein the programmable circuit is programmed to select the high impedance path or the low impedance path, wherein the capacitive path includes a low impedance driver, and wherein closing the switch increases a bandwidth of the programmable circuit.
