Abstract: Apparatus and methods for controlling overshoot in digital step attenuators are disclosed. By configuring a multi-bit DSA such that an attenuation control block changes a plurality of control signals in a manner preventing a series cascade of attenuation units from having a transient attenuation value less than an initial and final value of attenuation, an overshoot condition can be prevented. Control signals transition the attenuation units to a first state of attenuation before they transition attenuation units to a second state of insertion.
