The CP2128 is a low-noise, fixed-frequency step-up DC/DC converter designed for garden applications. It operates within an input voltage range of 2.7V to 4.5V and can generate a stable output voltage of 5V, with a maximum output current of...
The circuit is designed to be low cost. It uses a PIC12C508 to perform the control functions and standard 40 kHz piezo transducers. The drive to the transmitting transducer can be simply driven directly from the PIC. The 5V...
Circuit diagram of a modulator circuit in a transmitter and receiver of amplitude modulation. The modulator circuit in an amplitude modulation (AM) transmitter and receiver plays a crucial role in the process of encoding information onto a carrier wave. In...
For measurement purposes in the electronics laboratory, signals of various frequencies and waveforms are frequently required. A standard function generator typically provides sine, triangular, and square wave outputs. The frequency must be adjustable and should encompass at least the...
An LED (light-emitting diode) is utilized to illuminate keypad keys and LCD screen displays on all mobile phone handsets. It is controlled by the voltage or current drawn at its terminals. In the schematic diagram, the LEDs are driven...
A current source (MPF102) in the source lead of the bipolar transistor 2N3906 allows for precise control of drain current. The circuit incorporates an MPF102 JFET configured as a current source, which is connected to the source terminal of a...
