Abstract
The disclosure provides an RF receiver. The RF receiver includes an input driver. The input driver receives a coarse signal, and generates an input signal. A digital step attenuator (DSA) is coupled to the input driver and receives the input signal. An analog to digital converter (ADC) is coupled to the DSA. The DSA includes a sampling capacitor coupled to the ADC. The DSA also includes a time dependent resistor coupled to a source voltage and to the sampling capacitor.
