SQUARE WAVE DRIVER HAS FLEXIBLE OUTPUTS
This circuit can produce an output signal ranging from DC to 100KHz. It can source a
voltage ranging from 1v to 30v. It can sink a voltage ranging from zero volts to
–30v. It can drive up to 200ma of current and can even be switched to a floating
tristate output.

Sawtooth Generator Spans a 70 DB Range - 07/07/94 EDN-Design
Ideas....The circuit in Fig 1 demonstrates a simple method for generating a
voltage-programmable sawtooth waveform having a dynamic range greater than
70 dB. In addition to the sawtooth waveform, the circuit also produces
corresponding triangle- and square-wave outputs. The three ICs and
associated components.... [Design Idea by Paul Hendricks, Analog Devices,

series regulator with Q900 - This is a series regulator with Q900 being the
control element, Q901 a driver, and Q902 an error amp. ZD900 forms the emitter
reference voltage source. Since the generated high voltage and other voltages are
linked by means of the magnetic field of T900, any change in H.V. will be reflected
back to all of the other voltages. (added 02/05) |

Signal Controls Sine Generator - 05/15/03 EDN-Design Ideas....The circuit of
Figure 1 produces an accurate, variable-frequency sine wave for use as a
general-purpose reference signal. It includes an eighth-order elliptic,
switched-capacitor lowpass filter, IC3, which uses a 100-kHz square-wave clock signal
that microcontroller IC2 generates. (Any other convenient square-wave source is also
acceptable.... [Design Idea by Simon Bramble, Maxim Integrated Products, UK] |

Signal processor adds LED display - 6-Jun-96 Issue of EDN Designers
using the Texas Instruments TSS400, a versatile 4-bit sensor-signal processor, may
find the circuit in Figure 1 useful as a replacement for, or an adjunct to, the IC's
built-in display capabilities.... [Design Idea by N Thomas Christman, Zablocki VA

Signals Produce Pure Sine Waves - 10/09/97 EDN-Design Ideas.... Analog
oscillators produce excellent sine waves but are temperamental and hard to design.
They also require extensive redesign every time you change the oscillation frequency.
Digital oscillators are easier to design than analog oscillators, and digital signals
already exist in digital systems. Thus, it is often cost-effective.... [Design Idea by
Ronald Mancini, Harris Semiconductor, Melbourne, FL] |
