A direct conversion receiver for 60 GHz applications is fabricated in 65 nm CMOS. It consists of three low-noise amplifier gain stages, an RF mixer, a lowpass filter and a three-stage programmable gain amplifier. An overall minimum noise figure (NF) of 4.2 dB and maximum gain of 66 dB is achieved by the receiver occupying a core area of 0.26 mm 2 while drawing 36 mA of current from a 1 V supply.Introduction: The 7 GHz of unlicensed band around 60 GHz has spurred intense research activities relating to low-cost, low-power and highly integrated circuits for applications in ultra-high data-rate wireless communications. Recent studies have shown deep-scaled CMOS to be a promising technology for achieving a cost-effective monolithic solution [1]. To enable high-order modulation schemes (i.e. 16QAM and above), the receiver noise figure (NF) must be sufficiently low. However, the low NF should not come at the expense of excessive power consumption for portable applications. Consequently, a compact, low-noise, low-power consumption receiver design is highly desirable.Taking account of the above considerations, we have designed and implemented a low-noise, low-power receiver in 65 nm general purpose (GP) CMOS. As shown in Fig. 1, it is a direct-conversion receiver with a low-noise amplifier (LNA) tuned to 60 GHz followed by a mixer that down converts a RF signal to baseband with an external local oscillator (LO). The lowpass filter (LPF) and programmable gain amplifier (PGA) follow to complete the receiver chain. The prototype receiver achieves a maximum gain of 66 dB and a minimum NF of 4.2 dB with a compact area of 0.256 mm 2 , while dissipating 36 mW DC power from a 1 V supply. On-chip high quality factor transformers and inductors with small form-factors are used extensively in the receiver to boost gain, interface between stages and provide DC isolation. To optimise the receiver gain and NF with the minimal power consumption, non-unity transformer turn ratio is utilised to enable either voltage or current amplification according to circuit needs.
