A low power cross-coupled bandgap voltage reference is proposed in this paper. Based on the suggested structure, a 9.8 ppm/°C temperature coefficient bandgap voltage reference across −50°C to 150°C temperature range with 1.8-V supply voltage is achieved. For the help of the proposed cross coupled structure bandgap voltage reference, start-up circuit can be waived from which can save both area and...
A low-voltage, low-power single-ended LNA is implemented in a 0.25µm SOI CMOS technology. A theoretical basis for the design is used to develop design constraints in conjunction with a layout-aware design flow providing early insight into parasitic effects. The SOI CMOS LNA has a post-layout simulated noise figure of less than 3 dB; input IP3 of −10 dBm and small-signal gain of 19.2 dB within the...
The design and implementation of a CMOS continuous-time multiple loop feedback (MLF) leap frog (LF) filter is described. The filter is implemented using a fully-differential linear, low voltage operational transconductance amplifier (OTA). PSpice simulations using a standard TSMC 0.18 mum CMOS process with 1.8 V power supply have shown that the cut-off frequency of the filter ranges from 455 MHz to...
A 400 MHz CMOS fifth-order linear phase gm-c filter based on current-mode (CM) leapfrog (LF) structure is realized. The filter is implemented using a fully-differential linear operational transconductance amplifier (OTA) based on source degeneration topology. PSpice simulations in a standard TSMC 0.18 mum CMOS process and with 2.5 V power supply have shown that the cut-off frequency of the filter...
