2-Transistor Amplifier: A simple two-stage Amplifier. Use any
general-purpose NPN with high gain. It will drive low impedance headphones
directly. A speaker will probably require further boost. (added 10/05) |

3.3V converter delivers 3W from Li-ION battery : 11/05/98 EDN-Design
Ideas / (added 11/05) Lithium-ion batteries are rapidly gaining
popularity in portable applications because of their superior energy density, low
self-discharge rate, and high cell voltage. When you use one Li-ion battery to
power a 3.3V dc/dc converter; however, you encounter a problem, because the
battery voltage can be higher or lower than 3.3V. When fully charged, a Li-ion
cell has approximately 4.2V output; when fully discharged, the voltage is
approximately 2.5V. Therefore, you cannot use a simple buck or boost topology with
a single inductor to generate a regulated 3.3V output. Some designs boost the
voltage to approximately 4.3V and then use a low-dropout regulator to produce the
3.3V. This approach is inefficient, and efficiency is a crucial consideration in
battery-powered applications. The circuit in Figure 1 offers a solution to the
problem.... |

3-Band Equalizer: Using a single op-amp this easy to make equalizer
offers three ranges, low frequency, mid frequency, and high. With component values
shown there is approximately +/-20dB of boost or cut at frequencies of 50Hz, 1kHz
and 10kHz. Supply voltage may be anything from 6 to 30 Volts. Maximum boost 20dB
is only realized with maximum supply voltage. (added 4/05) |
