Abstract
System and method for analog signal generation and manipulation in an ultra-wideband (UWB) transmitter. A preferred embodiment comprises a digital portionof an UWB transmitter (for example, transmitter), which is responsible for encoding a data stream to be transmitted, and an analog portion. The analog portioncreates a stream of short duration pulses from the encoded data stream and then filters the stream of short duration pulses. To simplify the generation of the short duration pulses, a quantized representation of the short duration pulse is used. The quantized representation is created via the use of control signals that by coupling differential amplifiers together (such as amplifier), generate a voltage drop across a resistor (such as resistor) and hence, a current.
