Abstract
A programmable telemetry circuit that may be programmed for high bandwidth, low Q; low bandwidth, high Q; or for other parameters. The programmable telemetry circuit may include a first coil; 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; a capacitive path having a first node connected to a second node of the first coil; and an input path for coupling signals into the high impedance path, the low impedance path, and the capacitive path. The low impedance path may be connected in parallel with the high impedance path. The capacitive path may form a circuitous path with the high impedance path and the low impedance path. The programmable circuit may be programmed to select the high impedance path or the low impedance path.
