Abstract
An integrated circuit is provided for use in conjunction with an external antenna. The integrated circuit includes a memory circuit, a pulse sequencer, an NMR transmitter circuit and an NMR receiver circuit. The memory circuit is configured to store user-defined parameter data pertaining to an excitation period and an acquisition period that are part of an NMR pulse sequence. The pulse sequencer and the NMR transmitter circuit are configured to cooperate to generate RF signals in accordance the user-defined parameter data stored in the memory circuit, wherein such RF signals are supplied to the external antenna for emitting excitation signals from the external antenna during the excitation period of the NMR pulse sequence. The NMR receiver circuit is configured to receive electrical signals generated by the external antenna during the acquisition period of the NMR pulse sequence.
