Abstract: Disclosed herein is a voltage gain amplifier for use in an automotive radar receiver chain. The voltage gain amplifier utilizes pole-zero cancelation to yield a desired transfer function without gain peaking at a bandwidth in which attenuation is desired, and utilizes a low pass filter effectively formed by a feedback loop including a high pass filter and a differential amplifier to ensure the desired level of attenuation at the desired bandwidth. In some instances, a chopper may be utilized in the feedback loop prior to the high pass filter, and after the differential amplifier, so as to reduce the bandwidth of the differential amplifier in the feedback loop.
