In some embodiments, an attenuator can include a first group of attenuation steps with each attenuation step being configured to switchably provide a first attenuation value, and a second group of attenuation steps with each attenuation step being configured to switchably provide a second attenuation value less than the first attenuation value. The attenuator can be capable of providing a total attenuation value from approximately zero to a sum of the attenuation steps of the first group and the second group in increments of the second attenuation value. With such a configuration, a glitch can have a maximum magnitude that is a difference between the first attenuation value and the second attenuation value during a change in the total attenuation value.
