Abstract
There is provided an integrated circuit having a programmable gain amplifier and an embedded filter. The programmable gain amplifier and the filter comprise a gain element having an inverting input for receiving an input and a feedback signal, a non-inverting input coupled to ground, and an output. The gain element also has one or more feedback loops coupling the output of the gain element to the inverting input of the gain element. Each feedback loop has a switch coupled in series with at least one passive component. Each switch has a first state to connect the corresponding feedback loop and a second state to disconnect the corresponding feedback loop. Each switch is programmatically configurable to provide a first gain and a first bandwidth and a second gain and a second bandwidth such that the first bandwidth is substantially equal to the second bandwidth.
