Oscillator circuit for EEPROM high voltage generator

A semiconductor oscillator circuit comprising:

• a current generating circuit configured to provide a current that is inversely proportional to an operating temperature;
• a first and a second capacitor configured to be alternately charged by said current generating circuit;
• a first and a second switching circuit each having a first terminal coupled to said current generating circuit, a second terminal coupled to a ground terminal, a third terminal coupled to one of said capacitors, and a control terminal configured to receive a signal that dictates whether the capacitor is to be coupled to said current generating means or said ground;
• a first and a second voltage detection circuit coupled to each of said first and said second capacitors, said voltage detection circuit configured to issue an activation signal at an output terminal when a potential at an input terminal of said first or said second capacitors reaches a predetermined magnitude of voltage;
• and
• a complimentary switching circuit having a first and a second input terminal coupled to said output terminals of said first and said second voltage detection circuit and a first and a second output terminal each being coupled to one of said control terminals of said first and said second switching circuit, said first and said second output terminals configured to communicate complementary signals that are reversed every time an activation signal is received at one of said input terminals of said complimentary switching circuit.
