Abstract

This invention relates to a codeless and batteryless electronic pen and a transmitter-receiver of a tablet that calculates the position of the electronic pen by transmitting and receiving energy. A transmitter-receiver of a tablet comprises: an excitation signal generation unit for generating excitation signal that magnetizes the coils; a signal output circuit for alternatively outputting the excitation signal and the ground signal that enables the induced current to flow through the coil; a plurality of tri-state buffers for connecting the signal output circuit with the one ends of the coils; a buffer control unit for setting the output of the tri-state buffers either to a high impedance state or an enable state; a switching unit that turns on or off the connection between the other ends of the coils and the receiving signal amplifier that amplifies the induced current in the coil; and a switch control unit for controlling the switching unit.
