Abstract: A method for improving circuit stability is disclosed. In the method of the present invention, the circuit is analyzed to find the frequency band in which the input impedance at a target node behaves as a negative resistance, and then find the signal path of the frequency band in the matching circuit in front of the target node and add an attenuator in the signal path. This prevents the circuit from oscillation and improves the stability of the circuit. Furthermore, the signal on the main signal path will not be attenuated and the performance of the circuit will be maintained.

Abstract: A Bluetooth transmitter, a Bluetooth device, and a transmitter are provided. After being received by the transmitter, a transmission bitstream is modulated to generate a first-path modulated signal and a second-path modulated signal, which are up-converted to a first first-path up-converted signal, a second first-path up-converted signal, a first second-path up-converted signal, and a second second-path up-converted signal. The first first-path and the second first-path up-converted signals are corresponding to a first broadcast channel, and the first second-path and the second second-path up-converted signals correspond to a second broadcast channel. A first-path baseband signal is generated based on the first first-path and the second first-path up-converted signals, and a second-path baseband signal is generated based on the first second-path and the second second-path up-converted signals. A broadcast signal is generated based on the first-path and the second-path baseband signals.
