CMOS Integrated Switched-Mode Transmitters for Wireless Communication
The measured output power and efficiency of a 6 dBm 130nm CMOS class-D inverter chain was analyzed, utilizing gate bias variation to generate a pulse width modulated inverter output voltage (Cijvat et al., 2008). Efficiency versus output power was evaluated...
Digital-touch-on-off-switch
Only one LED can be illuminated when the circuit is at rest. The illuminated LED is determined by the touch pick-up that last had human contact. Pickup terminal A controls the on condition of LED1, while terminal B controls the...
Wilf Rigter`s SIMD1 V1
Normally the active high output from the inverter is used to enable the remainder of the CMOS gates which then perform some useful function. When the SIMD1 triggers at night, it snaps on and the output signal can be used...
cmos based vehicle anti theft alarm
This car alarm circuit includes Exit and Entry delays, an instant alarm zone, an intermittent siren output, and an automatic reset function. By incorporating external relays, it is possible to immobilize the vehicle and activate the lights.
The car alarm circuit...
Night security light
This simple circuit is built around a CMOS IC 4060 to obtain the required timing. During daytime, the LDR has low resistance and keeps pin 12 of IC1 high, preventing IC1 from oscillating. When it is dark, the LDR resistance...
DG509A Schematic for Monolithic Cmos Analog Multiplexers
Maxim's DG508A and DG509A are monolithic CMOS analog multiplexers. The DG508A is a single 8-channel (1-of-8) multiplexer, while the DG509A is a differential 4-channel (2-of-8) multiplexer. Both devices guarantee high performance and reliability.
The DG508A and DG509A analog multiplexers are designed...
Automatic plant waterer
The unit consists of a sensor, timer, and electric water pump. The sensor is embedded in the soil, and when dry, the electronics operate the water pump for a preset time. The circuit is composed of a level-sensitive Schmitt trigger,...
Cmos Piezo Driver Using 4049 Circuit
This circuit utilizes a 4049 integrated circuit (IC) to control a 2N2222 switching transistor. The transistor, in turn, drives a piezo transducer known as crystal 1.
The circuit design begins with the 4049 IC, which is a hex inverter capable of...
A Cmos Based Motorcycle Alarm circuit
This circuit provides an intermittent siren output with an automatic reset feature. It can be operated manually through a key-switch or a hidden switch, and it can also be configured to activate automatically when the ignition is turned off. By...
