Voltage amplification circuit

A voltage amplification circuit comprising:

• a first inverting amplifier placed in a first stage;
• a second inverting amplifier placed ma second stage, said second inverting amplifier being DC-coupled to said first inverting amplifier;
• wherein said first inverting amplifier comprises a first transistor with a drain and a gate of which are both connected to a terminal for a first potential and a second transistor with a gate of which is connected to an input node and with a source of which is connected to a terminal for a second potential, in which a source of said first transistor is connected to a drain of said second transistor, an output of said first inverting amplifier being placed between said source of said first transistor and said drain of said second transistor;
• wherein a second inverting amplifier comprises a third transistor with a drain and gate of which is connected to a terminal for said first potential and a fourth transistor with a gate of which is connected to a terminal for an output from said first inverting amplifier and with a source of which is connected to a terminal for said second potential, in which a source of said third transistor is connected to a drain of said fourth transistor, an output of said second inverting amplifier being placed between said source of said third transistor and said drain of said fourth transistor;
• and
• wherein a threshold value of said fourth transistor is larger than a threshold value of said second transistor.
