Wide Supply Range 32 kHz Oscillator

To generate a system clock or auxiliary sleep clock in microcontrollers (µCs) and low-power instruments we usually use A 32kHz oscillator. A CMOS inverter (74HC04 or CD4049UB type) biased as a linear amplifier by connecting a large-valued resistor from the input to the output is one of usual implementation. The inverter circuits give us problems.  To attain Supply currents fluctuate […]
