Voltage-limiting circuit with hysteresis comparator |
摘要 |
In a voltage-limiting circuit, the voltage to be limited is applied to the terminals of a resistive line, and the current flowing in this line is amplified by a current mirror that thus produces a reference current. A current-controlled voltage source receives this reference current and produces a reference voltage. This reference voltage is given to a hysteresis comparator that switches over for two distinct values of the voltage to be regulated. The disclosed device is particularly useful in the field of the load pumps used in electrically programmable memories.
