Abstract: A clock generator and a method to control an associated system are described. The clock generator (e.g., a PLL) can include a charge pump that can generate a current, and a controller coupled to the charge pump. The controller can determine a characteristic impacting operation of the clock generator and control the charge pump to adjust the current based on the determined characteristic to adjust a bandwidth of the clock generator. The clock generator and method can include adjusting the bandwidth to compensate for variations (e.g. PVT variations) that impact the operation of the clock generator to maintain constant or substantially constant bandwidth independent of such variations.
