Programmable phase generator for a radiation detector

A generator of phases of a detector, the generator integrating at least one elementary machine for interpreting a microcode stored in a register, each elementary machine comprising:

• at least one control input comprising a logic level change detector;
• at least one phase output comprising a controlled switch, enabling to define the logic level of the phase output, and a controlled inverter enabling to toggle the logic level of the phase output;
• at least one clock signal associated with a counter;
• a unit for loading the instructions and the arguments stored in the register, the instructions being coded over 3 bits and enabling to implement at least:
• an application of a logic level onto at least one phase output;
• a toggling of the logic level of at least one phase output;
• a synchronization with a logic change of a control input;
• a wait for a predetermined duration;
• and
• a restarting of a predetermined sequence;
• means for inhibiting the loading unit;
• and
• a unit for executing the instructions loaded by the loading unit, the execution unit being configured to:
• control the position of at least one controlled switch after an instruction of application;
• control the activation of at least one controlled inverter after an instruction to toggle;
• detect a logic change after an instruction of synchronization;
• control the inhibition of the inhibition means for a duration measured by the counter after a wait instruction;
• and
• control the position of a pointer of the loading unit after a restart instruction.
