Classification: G05F,Y10S

Abstract:
A start-up pulse generator comprising:a bistable reference circuit having an input terminal and an output terminal, and which outputs at said output terminal a first voltage level in a first steady state and a second voltage level in a second steady state;a monitor having an input terminal coupled to said reference circuit output terminal, and which outputs at an output terminal a first output signal upon receipt of said first voltage level and a second output signal upon receipt of said second voltage level;a hysteresis circuit having an input terminal coupled to said monitor output terminal, and an output terminal; anda start-up signal generator having an input terminal coupled to said hysteresis circuit output terminal, and an output terminal coupled to said reference circuit input terminal, and which provides a start-up signal to said reference circuit upon receipt of said first output signal.
