Abstract:
1. A semiconductor oscillator circuit comprising: a current generating means for producing a current at an output, said current being inversely proportional to an operating temperature; a first and a second charge storage means for storing electrical charge from said current generating means in an alternating sequence, said alternating sequence producing a frequency of said semiconductor oscillator circuit, said frequency being inversely proportional to said operating temperature; a first and a second current steering means for steering current, said first and said second current steering means configured to receive a control signal at a control terminal for determining a coupling of an output to an input terminal of each of said charge storage means to either said output of said current generating means or to a circuit ground terminal; a first and a second voltage detection means for producing an activation signal at an output upon attaining a predetermined magnitude of voltage by a potential at one of said input terminals of said charge storage means coupled to a respective input of said voltage detection means; and a complimentary switching means for producing a complimentary pair of control signals to said control terminals of said first and second current steering means, said complimentary switching means configured to toggle a potential of said complimentary pair of control signals at a receipt of said activation signal from either of said voltage detection means.
