“…To ensure that the down-converted product of the jamming signal in the receiver would not affect the signal-to-noise ratio (SNR), the following relationship should be satisfied [21] L < P Sig − P Int − SNR min − 10 log(BW) (1) where P Int is the power of the interference signal, P Sig is the power of the useful signal, and L is the phase noise of the LO signal. The required SNR min was 0.5 dB [22] and the channel bandwidth BW was 2 MHz. In IEEE 802.15.4 protocol, P Int is likely to be 20 dB and 30 dB greater than P Sig at 1 MHz and 3 MHz frequency offset, respectively, which resulted in the requirement of phase noise lower than −83.5 dBc/Hz and −93.5 dBc/Hz, respectively.…”

This paper presents a low-voltage ZigBee transceiver covering a unique frequency band of 780/868/915/2400 MHz in 180 nm CMOS technology. The design consists of a receiver with a wideband variable-gain front end and a complex band-pass filter (CBPF) based on poles construction, a transmitter employing the two-point direct-modulation structure, a Ʃ-Δ fractional-N frequency synthesizer with two VCOs and some auxiliary circuits. The measured results show that under 1 V supply voltage, the receiver reaches −93.8 dBm and −102 dBm sensitivity for 2.4 GHz and sub-GHz band, respectively, and dissipates only 1.42 mW power. The frequency synthesizer achieves −106.8 dBc/Hz and −116.7 dBc/Hz phase noise at 1 MHz frequency offset along with 4.2 mW and 3.5 mW power consumption for 2.4 GHz and sub-GHz band, respectively. The transmitter features 2.67 dBm and 12.65 dBm maximum output power at the expense of 21.2 mW and 69.5 mW power for 2.4 GHz and sub-GHz band, respectively.

“…This low power consumption standard aims at wireless sensing and control applications with low voltage and low data rates, including industrial and commercial uses, home automation, consumer electronics, and personal health care appliances. Because of the requirements of these articles, the sensors compliant to the ZigBee standard should be able to run for several months on just button cells or small batteries [20] and therefore should be low voltage and low power. The low supply voltage design guarantees that the sensors could operate for much more time and there would be no need for changing batteries as soon.…”

“…Therefore, for selection of channels, a 2 MHz bandwidth low-pass filter should be used to meet the requirement of 0 dB rejection at the adjacent channel (±5 MHz) and 30 dB rejection at the alternate channel (±10 MHz), respectively as shown in Figure 4 [20]. Assuming some margins, a third-order Butterworth filter with cutoff frequency of more than 1 MHz can be used for this purpose [20]. In order to provide some gain controlling feature to the receiver, this filter is designed to operate as a VGA, as well.…”

SUMMARYA low voltage bulk-driven operational transconductance amplifier (OTA) and its application to implement a tunable Gm-C filter are presented. The linearity of the proposed OTA is achieved by nonlinear terms cancelation technique, using two paralleled differential topologies with opposite signs in the third-order harmonic distortion term of the differential output current. The proposed OTA uses 0.8 V supply voltage and consumes 31.2 μW. The proposed OTA shows a total harmonic distortion of better than À40 dB over the tuning range of the transconductance, by applying 800 mV ppd sine wave input signal with 1 MHz frequency. The OTA has been used to implement a third-order low-pass Gm-C filter, which can be used for wireless sensor network applications. The filter can operate as the channel select filter and variable gain amplifier, simultaneously. The gain of the filter can be tuned from À1 to 23 dB, which results in power consumptions of 187.2 to 450.6 μW, respectively. The proposed OTA and filter have been simulated in a 0.18 μm CMOS technology. Simulations of process corners and temperature variations are also included in the paper.

“…As one of the most power-consuming components in Bluetooth, ZigBee or WiFi transceivers, VCO (Voltage Controlled Oscillator) with tiny silicon area, low supply voltage and power-consumption, also with acceptable phase noise (about −102 dBc/Hz@3.5 MHz at 10 mW transmit power) [1] has attracted great attention in 2.4 GHz band IEEE 802.15.4 standard fully integrated transceivers [1,2]. A lot of research [3,4,5,6] has been carried out to design 2.4 GHz VCOs with power saving structure but maintain the phase noise performance.…”

Based on the self-biased current-reuse complementary structure and interposed network, a low power LC voltage controlled oscillator (VCO) is presented, which can simultaneously achieve ultra-low power consumption and low phase noise. Firstly, thanks to the self-biased voltage-diving technique, the LC-VCO consumes ultra-low power consumption. Secondly, the novel interposed network can greatly improve the VCO's phase noise performance. The proposed VCO is implemented in SMIC 180 nm CMOS process with a small area of 0.15 mm 2 , which exhibits phase noise of −118.3 dBc/Hz at 1 MHz offset from the 2.5 GHz carrier at 0.8 V supply voltage while the power dissipation is only 0.23 mW.
