The A/D converter has a voltage controlled current source (16), a capacitor (18), a Schmidt trigger (22), a counter (6), and a transistor switch (20). The analog input voltage controls the voltage controlled current source. The terminal is coupled to the capacitor (18), the transistor (20), and the input of the Schmidt trigger (22). The other terminal of the capacitor (18) and the drain of the transistor (20) are coupled to the input of the counter (6). The output of the Schmidt Trigger is coupled to the input of the counter. The Reset clock (14) is coupled to the reset terminals of the Schmidt trigger (22) and the counter (6). The output of the counter represents the digital equivalent of the analog input. |
