More about Current (240)

| A current detector and a threshold switch are not sufficient when in comes to building an electronic fuse. Such a circuit would be trigger...

| Following the detailed description of the preamplifier in last month's installment, this second and final part of the article deals with t...

| The article describes a remote control (send/receive) system that does not use infra-red light, but visible light. It is particularly...

| The AD8037 is a rather special opamp because its positive and negative inputs have internal clamps. The clamp at the negative input is e...

| Monolithic integrated voltage-to-frequency converters or logarithmic converters often need a positive-direction input current. However,...

| Strictly speaking, the title 'current limiting' is not entirely right, since the circuit itself does not limit, but detects. When the cu...

| It is well known that the frequency of a crystal oscillator depends to some degree on the ambient temperature. AIthough this is often...

| This circuit enables a model train to shuttle continuously between two tracks. When the train travels from left to right across the track in...

| A particular difficulty with LED har displays is the high current drain. LED driver LM3914 controls a chain of LEDS instead of as usua...

| The upgrade consists of just a diode, but, if the internal system clock is used, it gives an improvement of some 6 dB in the THD+N measured...
