During the thesis, a two-staged analog baseband circuit incorporating a passive analog filter and a wideband voltage amplifier were successfully designed, implemented in an IC mask layout in a 65nm CMOS technology, and joined with a previously designed analog front-end design to form a wideband observation receiver. The baseband circuit is capable of receiving an IF bandwidth up to 990MHz produced by the analog front-end using low-side injection. The final circuit shows high IMD3 of at least 90 dBc. The voltage amplifier delivers a voltage amplification of 15 dB with around 0.08 dB amplitude precision over the bandwidth, while the passive filter is capable of a passband amplitude precision of 0.67 dB over the bandwidth, while effectively suppress signal images created by the mixer with at least 60 dBc. Both stages were realized in an IC mask layout, in addition, the filter layout were simulated using an EM simulator.
