clock generator circuit
The following diagram is the clock generator circuit diagram built using NAND gate logic integrated circuits (ICs). The circuit can utilize either the IC 7400, which is a TTL type, or the IC 4011, which is a CMOS type. The...
microcontroller How does this power supply circuit work? (MCU + LM317)
The filter consisting of resistors R1, R2, and capacitor C1 integrates the PWM waveform. The purpose of the operational amplifier appears to be that of a non-inverting amplifier, with the gain determined by resistors R6 and R7. However, the need...
SAA1057 PLL Synthesized FM Transmitter
The operation of the circuit is managed by a microcontroller from MICROCHIP, specifically the PIC16F84. This microcontroller supports buttons and a 2-line, 16-character LCD display, along with the PLL circuit SAA1057. The voltage-controlled oscillator (VCO) is implemented using transistor Q8,...
1-20 minutes a timing circuit
The system operates between 10 minutes to 2 hours, featuring a 100-line bell controlled by a multi-gear stick labeled S2 41f. The integrated circuit (IC) functions as a self-excited multivibrator. The device can manage binary pulses ranging from 3 to...
Precision Clock Generator
The device described can generate a complementary clock signal at frequencies ranging from 10Hz to 10MHz in factors of ten. It is referred to as the "10xHz clock generator," where 'x' is a number between 1 and 7. Additionally, the...
clock and Timing ICs
A sine wave can be derived from a square wave when necessary. One of the widely used integrated circuits for generating a clock signal is the MAX9471 from Maxim Integrated Products. The circuit below illustrates how to design a clock...
POWER LINE MODEM FOR COMPUTER CONTROL
This circuit employs an 87C57 microcontroller along with several peripherals to convert X-10 power-line carrier-code formats from a personal computer for use with an X-10 power-line interface in a home-control system. Software details can be found in the reference.
