    Is it possible to model a photodiode PIN InGasAS, in accord with datasheet, in simulator SPICE MicroCAP12?

    I want to know if it is possible to model a photodiode InGasAs panchromatic PIN , in accord with datasheet, in simulator SPICE MicroCAP 12.Because the supllier where I boughit it has not a SPICE model.And if it is possible, which are those steps. Here it is data-sheet...

    Monitoring car battery strength using Schmitt Trigger circuit

    Hi, i am new in analog designs. Now, i am trying to design a circuit using STC(Schmitt Trigger Comparator) circuit to monitor the voltage level of a car battery which normally is around 12 volts. Im trying to use two LEDs,green and red, to indicate the voltage level of the car battery. If the...

    IFC Engine- & enviroment analog sensordata to NME2000 bus through Teensy3.6 (marine application)

    Hello, I am working on a DIY project to interface a lot of signals to a NMEA2000 bus to be able to controle an older analog engine and other sensors with a new multi function display. To do so I am using Arduino / Teensy microcontroller together with a NMEA2K library. I started to design the...

    Voltage Controlled Voltage Sources (VCVS) - Power a Piezo Buzzer

    Hi, I am trying to power a Piezo Buzzer between 3.3VDC and 5VDC. The voltage is being adjusted so the sound is low (at 3.3VDC) and loud(at 5VDC). My attachment can be a little misleading. Alarm_low doesn't suggest the volume is low, just the number of beeps. Same holds true for Alarm_medium...

    Building a FM transmitter

    Hi, I am planning to build a FM transmitter for my school project. There are a lot of designs available on the internet and I simply don't know which to choose. I decided to choose a simple one from the cryptomuseum webpage. Its circuit is shown below. I am new to RF design. Please forgive my...
