0.14V Oscillator Circuit with Separate Logic Output Buffer
Description This circuit voltage EPAD MOSFET oscillator that operates 0.14V. this circuit U1A, form basic three-stage oscillator with feedback resistor capacitor network COSC output tapped buffered with output buffer stage. Power output stage supplied either different value, depending desired output high level. different voltage level, then output buffer also acts level shifter. minimize power consumption, value maximized proper output voltage-swing levels. Using threshold enhancement mode EPAD MOSFET, ALD110804 (quad with VGS(TH)= 0.40V), this oscillator operates 0.14V supply voltage power, frequency Capacitor COSC Resistor determine oscillating frequency oscillator, generally given fOSC COSC). However, EPAD MOSFET operating entirely subthreshold operating region MOSFET device. charging COSC limited R3+R4 discharging COSC limited current drive U1C. These factors tend decrease actual oscillating frequency significantly. remaining resistors through help determine power dissipation well oscillating frequency, optimized minimum power consumption circuit given desired frequency. Recommended Components EPAD MOSFET: ALD110804; COSC: MOhm R1,R2: 32MOhm; 40MOhm; 8Mohm; 400MOhm Other Related Circuit Ideas Schematic osc_42008.0 Nanopower (Colpitts) Oscillator Circuit
