摘要： The invention relates to a two stage class AB operational amplifier (200) for driving a load (L), comprising at least an input stage (201) comprising differential input terminals (IN+, IN−) and an output terminal (N) to provide a driving signal (VN). In addition, the operational amplifier comprises an output stage (202) comprising a first (A) and second (B) input terminals operatively associated to the input stage (201) to be driven on the basis of said driving signal (VN) and a driving circuit (203) operatively interposed between said input stage (201) and the output stage (202). The operational amplifier is characterised in that the driving circuit (203) comprises a first portion (204) comprising at least one resistor (R1) operatively connected between a first reference potential (Vcc) via a first circuitry block (MT, M11) comprising a PMOS transistor (MT) and a second reference potential (GND) via a second circuitry block (M12, MS) comprising a NMOS transistor (MS). The voltage drop (VR1) on said at least a first resistor (R1) is fixed to a value depending on said first (Vcc) and second (GND) reference potentials and the gate-source voltages of said PMOS (MT) and NMOS (MS) transistors, respectively. The driving circuit further comprises a second portion (205) comprising a first resistor (R2) and a second resistor (R2′) having first terminals connected one another in a common terminal (P) which is connected to the output terminal (N) of the input stage. Said first resistor (R2) has a second terminal connected the first input terminal (A) of the output stage and said second resistor (R2′) has a second terminal connected to the second input terminal (B) of the output stage. Said second terminals (A, B) of the first (R2) and second resistors (R2′) are connected to the first reference potential (Vcc) via a third circuitry block (MW, M9) and to the second reference potential (GND) via a fourth circuitry block (M10, MX), respectively. Said third (MW, M9) and fourth (M10, MX) circuitry blocks are arranged to be operatively connected to said first (MT, M11) and second (M12, MS) circuitry blocks, respectively, so that the voltage drop (VR2) between the second terminals (A, B) is substantially equal to the value of the voltage drop (VR1) across said at least one resistor (R1).

摘要： An electric circuit includes a supply terminal to receive an outer supply voltage and a voltage regulator coupled to the supply terminal and to provide supply and resting voltages. A lock-out circuit is switchable between active and inactive states and receives the supply voltage at a supply node to generate, in the active state, an output voltage on a output terminal thereof. A protection circuit protects against electrostatic discharge, having at least one first diode coupled between the supply node and the output terminal. A cut-off electronic lock couples, in the inactive state, the supply node to the supply terminal by reverse biasing the at least one first diode to make a voltage of the output terminal float.

The second number of bits is smaller than said first number of bits and a bit discarding unit is located downstream of the integrator stages and upstream of the derivative stages for discarding a given number of least significant bits from the bit words of the first signal before this is received by the derivative stages. Said given number is defined as the difference between said first and said second number of bits.
