“…Also, the higher order frequency components are attenuated by the PLC tank. In Figure 2, attempting to sense the down-converted component at the VCO output unavoidably degrades the phase noise [2]. One possible solution is to exploit the SLC network for the VCO to extract both LO and IF signals.…”

“…For highly integrated low-power receiver front-end, a current reuse technique is typically chosen across different functional blocks. A popular method is stacking the mixer on top of the input stage of the low-noise amplifier (LNA), while less frequent one is stacking mixer and voltage-controlled oscillator (VCO) [1][2][3][4]. In [1], a double balanced mixer is stacked on top of the voltage-controlled oscillator (VCO) by using the current reuse topology.…”

This paper proposes three types of single stage low-power RF front-end, called double-balanced LMVs, by merging LNA, mixer, and voltagecontrolled oscillator (VCO) exploiting a series LC (SLC) network. The low intermediate frequency (IF) or baseband signal can be directly sensed at the drain nodes of the VCO switching transistors by adding a simple resistorcapacitor (RC) low-pass filter (LPF). By adopting a double-balanced mixer topology, the strong leakage of the local oscillator (LO) at the IF output is effectively suppressed. Using a 65 nm CMOS technology, the proposed double-balanced LMVs (DB-LMVs) are designed. Oscillating at around 2.4 GHz ISM band, the phase noise of the proposed three DB-LMVs is −111 dBc/Hz at 1 MHz offset frequency. The simulated voltage conversion gain is larger than 36 dB and the double-side band (DSB) noise figure (NF) is less than 7.7 dB. The DB-LMVs consume only 0.2 mW dc power from 1-V supply voltage.

This paper proposes three kinds of single stage RF front-end, called quadrature LMVs (QLMVs), by merging LNA, single-balanced mixer, and quadrature voltage-controlled oscillator (VCO) exploiting a series LC (SLC) network. The low intermediate frequency (IF) or baseband signal near dc can be directly sensed at the drain nodes of the VCO switching transistors by adding a simple resistor-capacitor (RC) low-pass filter (LPF). Using a 65 nm CMOS technology, the proposed QLMVs are designed. Oscillating at around 2.4 GHz band, the proposed QLMVs achieve the phase noise below -107 dB/Hz at 1 MHz offset frequency. The simulated voltage conversion gain is larger than 30 dB. The double-side band (DSB) noise figure (NF) of the proposed QLMVs is below 10 dB. The QLMVs consume less than 0.51 mW dc power from a 1-V supply.

A 1.2 V high conversion gain mixer which reuses the gm stage of the mixer as RF and IF amplifying stage is proposed in this paper. The gm stage of the proposed mixer converts the input RF voltage into current and also amplifies the down-converted IF signal. A high-pass network and a low-pass network are used in the mixer to block the RF signal and IF signal respectively in order to guarantee frequency stability. This mixer was designed and fabricated in 65 nm CMOS process. The measured IIP3 and DSB NF are À16 dBm and 13.5 dB respectively. A high conversion gain of 30 dB is achieved with the power consumption of 3 mW under a 1.2 V supply voltage.
