A co-design strategy for the implementation of a low-voltage fully integrated CMOS receiver is presented. This co-design approach allows the design of a compact direct-conversion receiver by avoiding 50 α matching buffers and networks, and AC coupling capacitors between mixer inputs and LNA and oscillator outputs. Moreover, the proposed circuit does not require DC choke inductors for mixer biasing. Since a 1.2 V power supply is used, a current bleeding technique is applied in the LNA and in the mixer. To avoid inductors and obtain differential quadrature outputs, an RC two-integrator oscillator is employed, in which, a filtering technique is applied to reduce phase noise and distortion. The proposed receiver is designed and simulated in a 130 nm standard CMOS technology. The overall conversion voltage gain has a maximum of 35.8 dB and a noise figure below 6.2 dB.
