A ferro-electric tunable antenna matching circuit is provided for a multi-band antenna. The system may be implemented using a single instrument, or a combination of instruments, such as video waveform monitors and video signal generators. At least one de-coupling transistor is configured to de-couple the buffer from the bit line, and the de-coupling transistor is formed in the well. The task query response may include an indication that the first server is storing a task associated with the second client device.
