Read amplifier including differential transistor circuit with inductive and unidirectionally conductive load arrangement

Claim 1

A READ AMPLIFIER CIRCUIT COMPRISING A SOURCE OF INPUT SIGNALS, FIRST AND SECOND TRANSISTORS EACH HAVING A CONTROL ELECTRODE COUPLED TO SAID SOURCE OF SIGNALS AND EACH HAVING A LOAD CURRENT PATH, A SOURCE OF SUBSTANTIALLY CONSTANT CURRENT COUPLED TO FIRST ENDS OF THE LOAD CURRENT PATHS OF SAID FIRST AND SECOND TRANSISTORS, A POINT OF POTENTIAL, FIRST AND SECOND INDUCTORS, RESPECTIVELY COUPLED BETWEEN THE SECOND ENDS OF THE LOAD CURRENT PATHS OF SAID FIRST AND SECOND TRANSISTORS AND SAID POINT OF POTENTIAL, A FIRST DIODE HAVNG AN ANODE TO CATHODE PATH COUPLED RESPECTIVELY BETWEEN THE SECOND ENDS OF THE LOAD CURRENT PATHS OF SAID FIRST AND SECOND TRANSISTORS, A SECON DIODE HAVING AN ANODE TO CATHODE PATH COUPLED RESPECTIVELY BETWEEN THE SECOND ENDS OF THE LOAD CURRENT PATHS OF SAID SECOND AND FIRST TRANSISTORS, AND DIFFERENTIAL MEANS COUPLED TO THE SECOND ENDS OF THE LOAD CURRENT PATHS OF SAID FIRST AND SECOND TRANSISTORS.
