Abstract
An integrated step attenuator ('ISA') monolithically integrated on a single chip for adjusting an input signal. The ISA may include a step attenuation network ('SAN') that may include at least one switchable attenuation section, and at least one electronically switchable trimming network (“ESTN”). The SAN may be configured to adjust the input signal responsive to the state of a switch that bridges the attenuation sections of the SAN, and the ESTN may be configured to adjust the input signal responsive to the state of a switch in signal communication with one or more shunt resistors in the ESTN.
