ABSTRACT:
This invention is a voltage divider circuit having an input voltage at a first terminal (V.sub.IN) and an output voltage at a second terminal (V.sub.OUT). The circuit includes a parallel-connected first resistor (R.sub.1) and first capacitor (C.sub.1) coupled between the first and second terminals (V.sub.IN,V.sub.OUT) and a parallel-connected second resistor (R.sub.2) and second capacitor (C.sub.2) coupled between the second terminal (V.sub.OUT) and a reference (V.sub.REF). The ratio of the ohmic value of the second resistor (R.sub.2) to the sum of the ohmic values of the first and second resistors (R.sub.1,R.sub.2) is substantially equal to the ratio of the value in farads of the first capacitor (C.sub.1) to the sum of the values in farads of the first and second capacitors (C.sub.1,C.sub.2).
