An improved charge pump based phase locked loop where the loop filter resistor noise is reduced by about an order is presented. The voltage controlled oscillator generates a clock signal, and this is input to the phase detector, which, compares the oscillator clock with the reference clock and using the Charge pump it generates a current output proportional to the phase difference. The loop filter converts this proportional current to a voltage and connects it to the oscillator input. The loop filter consists of a capacitor, resistor and the apparatus that bypasses most of the resistor noise.
